Outsourcing bookkeeping and VAT under MTD: what to hand over

• MTD for VAT is live. MTD for Income Tax is phasing in; check the current timetable on gov.uk before you promise a client anything.
• Hand over the processing: bank recs, ledgers, supplier statements, VAT return preparation and the digital-links housekeeping.
• Keep the relationship, the scheme decisions, anything that is advice, and the decision to press submit.
• Work in your own software under individual logins. Never hand over your master credentials.
• A weekly routine and a disciplined query list matter more than which provider you pick.

Where MTD has left bookkeeping

Making Tax Digital for VAT has been live long enough that most practices have stopped talking about it. Digital records, digital links from record to return, submission through compatible software. The argument about whether it would happen is over.

MTD for Income Tax is the next wave, bringing quarterly updates for sole traders and landlords above thresholds that HMRC sets and adjusts. We are deliberately not stating the dates or the thresholds here, because they have moved before and they will be wrong by the time you read this. Check the current timetable on gov.uk and plan from that.

What both waves have in common is this: the bookkeeping has to be kept properly, in software, all the time. The old model of catching up twelve months of records in a fortnight before the accounts are due does not survive quarterly reporting. That makes bookkeeping a steady, recurring processing job, which is exactly the kind of work that outsources well. It also means more of it, which is why practices are looking at it now.

What to hand over

The rule is simple. If a competent bookkeeper who does not know the client can do it from the records and a clear brief, it can go. If it needs a conversation with the client or a judgement about their affairs, it stays.

Bank reconciliations

The core of it. Feeds pulled in, transactions matched, coded, and the unreconciled list worked down to nothing or to a short query list. Weekly for anything with real volume, fortnightly at the least. If the bank rec is current, everything else is easier.

Purchase and sales ledgers

Supplier bills captured through Dext, AutoEntry or the software's own capture, coded, matched to payments. Sales invoices raised from the client's source data where the practice does that, or checked where the client raises their own. Aged creditors and debtors kept honest.

Supplier statement reconciliations

Unglamorous, always behind, and the thing that catches duplicate bills and missed credit notes. Hand it over with a list of the suppliers that matter.

VAT return preparation

Running the return in the software, checking the figures against the ledgers, flagging anything odd: a big capital purchase, a zero-rated sale that looks standard-rated, a supplier invoice with no VAT number, a box figure that has moved a lot against last quarter. The output is a draft return and a short note of what to look at. Not a submission.

Digital-links housekeeping

Where a client keeps part of their records outside the main software, a spreadsheet of till takings say, someone has to make sure the link into the return is digital and not retyped. That is checking, tidying and documenting. Good outsourced work.

Client record chasing, to a point

Chasing the missing bank statement or the bill with no image can be done by the outsourced team under your practice name, with your templates and your tone. Chasing the client who has not paid you cannot. Decide which is which up front.

What to keep

The client relationship

Your client deals with your practice. The outsourced team works behind that, white-label, in your name. If a client needs to talk through why their VAT bill has doubled, that is you.

VAT scheme decisions

Whether a client should be on flat rate, cash accounting, annual accounting, or standard; whether they should register early or deregister; partial exemption method. These are advice. They carry your professional responsibility and they need the client's circumstances in full. The outsourced team can prepare the numbers that inform the decision. It should not make it.

Anything that is advice

Treatment of an unusual transaction. Whether something is capital or revenue. Whether a cost is allowable. Anything that starts with "what should the client do about". Keep it in the practice, with a reviewer's name on it.

The submission decision

Pressing submit on a VAT return is an act with consequences. Your practice is the agent. The outsourced team prepares; the practice reviews and files, or explicitly delegates filing under a written authority with a named reviewer. At Muckin, every job is reviewed and signed off in the UK before it reaches the practice, and then the practice makes the call. That is deliberate. See how it works.

Software access done properly

Every mainstream platform supports this. Xero, QuickBooks Online, Sage Business Cloud, FreeAgent all let you add a user with a defined role. Dext and AutoEntry have team user roles. Use them.

• Individual logins. One named user per person. No shared practice login, ever. You need an audit trail that says who changed what.
• Least privilege. A bookkeeper role does not need to see payroll or change bank feed settings. Give the access the job needs and no more.
• Multi-factor authentication on. Every account. No exceptions.
• Access through the practice's own subscription. The data stays in your tenancy. When the arrangement ends, you remove a user. Nothing has to be migrated back.
• No exports to personal devices. Work happens in the software. If a report needs to leave, it goes through the practice's own file storage, not email or a messaging app.

We have written a fuller guide to data security and GDPR when outsourcing. Read it before you hand over a single login.

A weekly routine that holds up

This is the bit that decides whether outsourcing works. Not the contract. The rhythm.

1. Monday: feeds and capture. Bank feeds refreshed and checked for gaps. Dext or AutoEntry inbox cleared, items pushed through and coded.
2. Tuesday to Thursday: reconciliation. Bank recs worked across the client list in a fixed order, highest-volume first. Supplier statements for the clients due a VAT return this quarter.
3. Friday: query list and status. One consolidated query list per client, sent to the practice, not to the client unless that has been agreed. A one-page status: what is reconciled to what date, what is blocked and why.

One to two hours ahead of UK time, a Pretoria-based team has your Monday feeds checked before your office opens. That is a small thing that turns out to matter on a Friday before a VAT quarter closes.

Query-list discipline

Queries are where bookkeeping outsourcing goes wrong. Too many, sent too often, badly worded, and the client stops answering. Then the rec stalls, the return is rushed, and the practice blames the provider.

• One list per client, one send per week. Not five emails on five days.
• Each query has a date, an amount, a payee and a specific question. "What is this?" is not a query. "£480 paid to J Smith on 14 March, no invoice, is this a subcontractor?" is.
• Suggested treatment included. "We have coded to drawings pending your reply." The client corrects rather than starts from nothing.
• Open items aged. Anything over three weeks is escalated to the practice, because it is now a relationship problem, not a bookkeeping one.
• Recurring queries become rules. If the same payee needs the same answer every month, write the rule in the client's notes and stop asking.

The quarterly cadence

With MTD for VAT, and MTD for Income Tax as it phases in, the quarter is the unit of work. Build around it.

• Week 1 of the quarter: previous quarter's return prepared, reviewed, submitted by the practice. Any adjustments posted. Bank recs brought fully current.
• Weeks 2 to 10: steady weekly routine. Nothing heroic.
• Weeks 11 to 12: pre-quarter-end sweep. Chase outstanding queries hard. Reconcile every supplier statement that matters. Flag clients whose records are not in a fit state so the practice can have the conversation before the deadline, not after.
• Quarter-end plus a few days: draft return and exception note to the practice.

A practice with thirty VAT-registered clients is running a small production line. Treat it like one. The capacity calculator will tell you roughly how many hours a month that line needs; at market fee levels we see for bookkeeping, £100-300 a month per client and £70-200 a quarter for VAT (our estimate from running a practice), the margin depends entirely on keeping the hours per client down, and the hours come down when the routine is steady.

What it costs

Per-job offshore VAT return rates on the market run about £25-60 a return. That is fine for a handful. Once you have real volume, a dedicated person is usually cheaper per client and far easier to manage. A Muckin Production seat is £1,950 a month for 160 hours, £1,100 for 80, £650 for 40, rolling monthly with a month's notice, full details on the pricing page. Against a UK bookkeeper at £36-44k all-in, that is the whole case, and you decide the hours.

Where to start

Put your bookkeeping and VAT client counts into the capacity calculator to see the hours. Then talk to us about which clients to move first; we usually suggest starting with the five cleanest and building the routine before adding the messy ones. We muck in from the first bank rec.
