How accountants can get client receipts into Sage — without chasing
Every South African practice knows the bottleneck. It isn't the bookkeeping, the VAT treatment or Sage itself. It's getting the receipts out of the client in the first place. Here's how to close that gap by meeting clients where they already are — WhatsApp — and letting their slips flow into Sage on their own.
- The bottleneck is client submission, not the accounting.
- Clients already use WhatsApp — so capture should live there.
- Receipts post to each client's own Sage company, documents attached.
- Not a Dext replacement — an adoption fix for the clients who never submit.
The real bottleneck in a Sage practice
You can be excellent at Sage and still lose hours every month to something upstream of the ledger: the client who promises to "send everything through" and doesn't, the shoebox that arrives at year-end, the WhatsApp photo of a slip you then have to capture by hand. The accounting is the part you're good at. The chasing is the part that erodes your margin and your patience.
The instinct is to hand the client software — a portal, an app, a login. For a certain kind of client that works. For the driver, the tradesperson, the spaza owner, the busy founder who lives in their inbox and WhatsApp, it doesn't: another app is another thing they won't open, and the receipts still don't come.
Meet the client on WhatsApp
The reframe that fixes this: stop asking clients to come to your tools, and put capture where they already are. In South Africa that's WhatsApp — near-universal, familiar, already open on their phone. SlipStack gives each client a WhatsApp number to photograph slips to. No app, no login, no training call. They snap and send, the way they already send you photos of slips — except now it doesn't land as an admin job on your desk.
From there it's automatic: SlipStack reads the supplier, date, amount and VAT, the figures are confirmed, and the expense posts into that client's own Sage Accounting company with the receipt attached. The original PDF is filed to Drive, sorted by month, so the audit trail is intact. You move from chasing and capturing to reviewing.
Where this fits against Dext and AutoEntry
Be clear-eyed about this, because it matters for a practice. Dext and Sage's own AutoEntry are powerful: invoice fetching, supplier statement matching, line-item extraction, approval workflows. If your firm runs complex accounts payable for clients, those tools do things SlipStack doesn't, and you should use them.
SlipStack isn't trying to replace that suite. Its single edge is adoption — it solves the specific, expensive problem of the clients who never submit their receipts at all, by making capture as easy as sending a WhatsApp photo. Many practices run both: the full suite for the clients who'll use it, and WhatsApp capture for the ones who won't. The measure that matters isn't feature count; it's how many receipts actually arrive.
A practical way to trial it
You don't have to roll this across the practice on day one. Pick one or two of your worst-submitting clients — the ones whose year-ends you dread — and put them on WhatsApp capture into their Sage company. If the receipts start arriving on their own, you'll know quickly, and on the exact clients where it's worth the most. SlipStack is early software built in the open, and its Sage posting is newer than its Xero path, so a small trial is the honest way to start.
Give each client a WhatsApp number for their slips. SlipStack reads and confirms them, posts into that client's Sage Accounting company with the receipt attached, and files the original to Drive — so you stop chasing and start reviewing. More for accountants →
