7 Tools Accountants Use to Manage Making Tax Digital for All Their Clients at Once

Making Tax Digital is no longer something practices can prepare for gradually. With Income Tax Self Assessment obligations arriving in waves and VAT compliance already well underway, the question for most accountants is not whether to get organised but how. Managing MTD across a full client base requires more than good intentions.

The right combination of software can make an enormous difference, not just for keeping up with HMRC requirements but for running a practice that feels in control rather than constantly reactive. The seven tools below represent the range of options accountants are turning to, from comprehensive compliance platforms to the smaller but meaningful pieces of the puzzle.

Sage for Accountants

Sage for Accountants is purpose-built for practices managing MTD obligations across multiple clients simultaneously. The platform gives accountants a centralised view of every client's compliance status, upcoming deadlines, and submission history from a single dashboard, eliminating the need to jump between systems or maintain manual tracking spreadsheets.

Direct Integration With HMRC's MTD Gateway

The connection to HMRC's Making Tax Digital gateway is built directly into the platform, meaning quarterly updates and VAT returns can be submitted on behalf of clients without leaving the software. Sage's bridging functionality also accommodates clients who have not yet moved to fully cloud-based bookkeeping, allowing them to become compliant without requiring an immediate and disruptive change to how they manage their own records.

Each client profile within the platform holds their MTD obligations, filing history, and linked documentation in one place. Permissions can be configured so that clients access only what is relevant to them, while the practice retains full oversight. Any team member can step in and continue work on a client file without needing a handover, which matters considerably in a busy practice.

Onboarding Built Around Real Practice Workflows

Sage has invested in making client onboarding as practical as possible. New clients can be brought onto the platform through guided steps that reduce the back-and-forth that typically delays the transition to digital. The interface is clean and approachable enough that clients interacting with their own data rarely require significant support from the accountant.

For practices looking for a single platform to anchor their entire MTD operation, Sage for Accountants is the most complete option available. Its depth of HMRC integration, client management capability, and practice-wide visibility set a standard that the other tools in this list, useful as they are, are designed to complement rather than match.

Calendly

Calendly is a scheduling platform that removes the coordination overhead from booking client meetings. Rather than exchanging multiple messages to find a mutually available time, the accountant shares a link and the client selects a slot directly from a live calendar, with confirmations and reminders handled automatically.

Reducing the Hidden Cost of Diary Management

In an MTD context, practices are running significantly more touchpoints with clients than they were under annual return workflows. Onboarding calls, quarterly review check-ins, and ad hoc compliance conversations all need to be scheduled, and the cumulative time spent arranging those meetings across a large client base is not trivial. Calendly integrates with most calendar systems and video-conferencing tools, so the entire booking process resolves itself without manual input.

The platform supports multiple meeting types with different durations and purposes, which is useful for practices that want to distinguish between a brief onboarding call and a more substantive annual review. Round-robin assignment allows incoming bookings to be distributed across a team, and buffer settings prevent back-to-back appointments from becoming the norm.

A Practical Piece of a Larger System

Calendly does not touch HMRC submissions or compliance tracking, so its contribution to an MTD workflow is focused rather than broad. What it does well is eliminate a specific category of administrative friction that, scaled across dozens of clients and recurring quarterly cycles, adds up quickly. Practices that pair it with a dedicated compliance platform will find it a reliable and low-maintenance addition.

Karbon

Karbon is a practice management platform designed to give accounting firms structured visibility over their workflow, team capacity, and client communications. It is built around the idea that the practice as a whole should have a clear picture of what work is in progress, who is responsible for each task, and where delays are developing.

Workflow Templates and Team Coordination

For practices managing MTD across a large client list, Karbon's ability to templatise recurring processes is a meaningful feature. A quarterly update workflow can be built once and rolled out consistently for every relevant client, reducing the risk of steps being skipped and making it easier to maintain quality as the team grows. Tasks link to client records, giving managers a real-time view of where each piece of work stands.

Karbon also surfaces client email communication to the wider team by connecting to shared inboxes, rather than leaving correspondence buried in individual email accounts. This is particularly valuable when a team member is absent or a client query needs to be picked up by a colleague unfamiliar with the account.

Strong Internal Tooling With a Narrower Compliance Scope

Where Karbon is more limited is in its direct MTD functionality. It does not connect to HMRC's gateway, so practices with high submission volumes will need a specialist compliance platform running alongside it. Karbon's value is in how work is managed and coordinated internally, and for practices whose primary challenge is visibility and organisation rather than submission handling, it offers a thoughtfully designed solution.

Adobe Sign or DocuSign

Adobe Sign and DocuSign are electronic signature platforms that allow documents to be prepared, sent, signed, and returned without any paper changing hands. Both carry legal recognition in the UK and are in wide use across professional services for engagement letters, client authorities, and other formal agreements.

Accelerating the Onboarding Process

Bringing a new client onto an MTD-compliant workflow typically requires signed documentation before anything substantive can begin. The traditional process of printing, posting, and waiting can add days to an onboarding timeline that would benefit from moving quickly. Both Adobe Sign and DocuSign reduce that process to minutes, with the client signing from any device and the completed document returned instantly.

Audit trails accompany every transaction, capturing when a document was sent, opened, and signed. This creates a reliable record for professional liability purposes and removes any ambiguity about whether a client has formally authorised a particular course of action. Document templates can be configured for the forms used most frequently, which further reduces preparation time.

A Focused Contribution to a Broader Workflow

E-signature tools do not engage with HMRC submissions or compliance tracking in any direct way. Their role is to remove friction from a specific administrative step, and within that scope they perform reliably and with minimal setup. Practices that are still routing documents through post or relying on scanned wet signatures will find the transition to either platform straightforward and immediately beneficial to turnaround times.

Liscio

Liscio is a client communication and document management platform built specifically for accounting firms. It provides a secure, branded portal through which clients can upload records, respond to requests, sign documents, and exchange messages with their accountant, all without the practice relying on email or requiring clients to navigate complex login procedures.

A Cleaner Experience for Client Document Sharing

The mobile-first design of Liscio reflects the reality that many clients, particularly sole traders and landlords, are not managing their affairs from a desktop. Being able to photograph a receipt or upload a bank statement directly from a phone, and have it arrive securely in the accountant's workflow, removes a step that often creates delays. For quarterly MTD updates where timely receipt of information matters, this kind of accessibility has real operational value.

Request tracking within the platform gives practices a clear view of what has been asked for, what has been received, and who still needs to respond. As a quarterly deadline approaches, accountants can send targeted document requests and monitor responses without resorting to manual follow-up logs or chasing by phone.

A Complement to the Core Compliance Layer

Liscio is not designed to connect to HMRC or manage submissions. It operates at the client-facing layer of the practice workflow, improving how information flows between accountant and client rather than how that information is ultimately processed and filed. Practices that already have their compliance infrastructure in place and are looking to improve the client experience will find Liscio a well-considered addition.

Dropbox Business or SharePoint

Dropbox Business and Microsoft SharePoint are cloud-based storage and collaboration platforms used across many industries, including professional services. Both provide practices with a secure environment for organising, storing, and sharing large volumes of client documents and internal files.

Infrastructure for Digital Record-Keeping

MTD requires that businesses keep digital records, and for the practice managing those records on behalf of clients, having a reliable and well-organised storage system underpins everything else. Both Dropbox Business and SharePoint handle large file volumes, support folder structures that mirror client hierarchies, and provide version control so that earlier iterations of documents remain recoverable. SharePoint's native integration with Microsoft 365 makes it a natural fit for practices already working in Word, Excel, and Outlook on a daily basis.

Dropbox Business appeals particularly to practices that value simplicity and ease of external sharing. Sending a client or external advisor access to a specific folder takes only a few clicks, and the interface requires almost no training to use confidently. Both platforms offer administrative controls that allow practices to manage permissions carefully across their team and client base.

A Foundation Layer, Not a Compliance Solution

Neither Dropbox Business nor SharePoint connects to HMRC or handles MTD submissions. Their value is as infrastructure rather than as compliance tools, providing the organised, accessible digital environment in which the rest of the practice workflow operates. Used alongside a dedicated practice management or compliance platform, they help ensure that documents are where they need to be when they are needed.

Bright: CPD and Training Platform

Bright is a continuing professional development platform designed for accounting and finance professionals in the UK. It offers accredited courses, webinars, and structured learning pathways covering technical topics across the profession, including the evolving requirements of Making Tax Digital.

Staying Current as MTD Continues to Develop

MTD is not a static framework. HMRC has updated its requirements, timelines, and guidance at various points since the initiative was introduced, and the transition to Income Tax Self Assessment represents another significant shift that practices need to understand thoroughly before advising clients. Bright provides a structured way for practice staff to engage with those changes rather than piecing together updates from disparate sources.

The platform's content is written for accounting professionals rather than a general business audience, which means the material is directly applicable rather than requiring translation into a practice context. CPD hours are tracked automatically, which is administratively useful for firms that need to demonstrate ongoing professional development as part of their regulatory obligations.

The Long-Term Value of a Well-Informed Team

A practice team that understands MTD requirements with confidence is better placed to advise clients clearly, handle technical queries without hesitation, and anticipate changes before they create compliance gaps. Bright's contribution to MTD readiness is through the people using the tools rather than through the tools themselves, and that kind of investment tends to compound in value over time. For practices that take professional development seriously, a dedicated platform for it is more reliable than ad hoc attendance at occasional events.

Building a Tech Stack That Works as Hard as You Do

Each tool in this list addresses a genuine need within the MTD challenge, whether that is staying informed, communicating with clients, managing documents, or keeping the team coordinated. None of that infrastructure matters, however, without a foundation that handles the compliance work itself: the HMRC submissions, the client oversight, and the deadline management that MTD demands at scale. Sage for Accountants provides that foundation, and the most effective practice tech stacks tend to be the ones built around it.

Frequently Asked Questions

Can I manage all my clients from one platform, or do I need separate software for each one?

The right practice management software makes it possible to oversee your entire client base from a single interface. Sage for Accountants is built with exactly this in mind, providing a centralised view of every client's submissions, upcoming deadlines, and compliance status without requiring you to log in and out of different accounts for each individual.

Is HMRC-recognised software the same as MTD-compliant software?

For all practical purposes, yes. HMRC publishes a list of software products it has verified as capable of submitting data through the official Making Tax Digital gateway. Before selecting any tool for your practice or recommending one to clients, it is always worth checking that it appears on that list. Sage is among the most well-established names on it.

How do I keep up with changes to MTD requirements as they are introduced?

HMRC revises its guidance regularly, and the MTD framework has shifted considerably since it was first launched. Combining a subscription to HMRC's agent update with accredited CPD training and a relationship with a software provider that communicates regulatory developments proactively gives practices the most reliable coverage. Sage takes that kind of ongoing communication with users seriously.

What does a good MTD onboarding process look like for a new client?

The most effective onboarding processes tend to be ones that minimise the burden placed on the client. This means using a platform that guides both the accountant and the client through clear, logical steps, collecting any necessary signed authorities digitally, and establishing a secure channel for ongoing document sharing early on. Clients who are walked through the process rather than handed a list of instructions tend to engage with it far more willingly, and that early goodwill pays dividends when quarterly deadlines start arriving.

What if some of my clients are reluctant to go digital?

Resistance from clients is one of the most frequently cited challenges in MTD transition conversations, and it is rarely as fixed as it first appears. The most effective approach is to make the change feel as uncomplicated as possible, choosing software with a clean and approachable interface and a secure portal that does not require clients to develop any new technical skills. Most accountants find that once clients experience how straightforward a quarterly digital update is compared to the pressure of an annual deadline, any remaining reluctance tends to resolve itself naturally.

How long does it typically take to bring an existing client base onto MTD-compliant software?

The honest answer is that it varies considerably depending on the size of the practice, the complexity of individual clients' affairs, and how much groundwork has already been done. Practices that approach the transition systematically, prioritising clients with the earliest compliance obligations and using a platform designed to streamline onboarding, tend to move through their client base far more efficiently than those working without a clear process. Starting earlier than feels strictly necessary almost always proves to have been the right decision.
