Sitting invoices are arithmetic, and arithmetic at 10pm goes wrong.
Eleven days, two visits a day, except the Tuesday they came back early and the Saturday you did an extra because the flight was delayed. Plus the bag of food you bought and the vet trip you drove them to. Every one of those is a number you are reconstructing from memory and a text message, and every one is a chance to under-charge yourself.
Counting visits by hand
From a calendar that was never meant to be totalled.
The extras get dropped
The food, the litter, the mileage to the vet. Awkward to itemise, so often not billed.
And the numbering
A spreadsheet column and good intentions, which HMRC is not fond of.

The visits have already counted themselves.
- Unbilled work per client, with what it is and what it totals
- Invoice one client, one period, or every client with unbilled work at once
- Nothing is emailed by the run — you get drafts to check first, and send each one yourself
- Every visit as its own line, with the date and the animal
- Late cancellation fees carried through alongside the visits
- Extra visits you did outside the schedule are caught — flagged as needing a price, not silently billed at nothing

A manual invoice for the things a visit record cannot hold.
The bag of food, the litter, the key cutting, the vet run, the work you did before you ever installed this. All of it can be invoiced without leaving the sequence.
- Type a line, set a price, issue it — from the same numbering
- Add more lines to a draft before it goes
- No gap in your sequence from invoicing something outside the app
- An empty invoice can never take a number

A document a client can pay from, and a screen that says who hasn’t.
- Your logo, business name, address, terms and footer
- VAT number and rate where you are registered, absent where you are not
- 27 supported currencies, stamped on when the invoice is issued
- Bank details, PayPal, or a payment link from your own provider
- Emailed in your name with the PDF attached, replies coming to you
- Outstanding, overdue, paid and void, with payment date and method
- Optional reminders: nothing before the due date, at most three, then it stops
Straight about what it does not do
CorePaw does not process payments, so there are no saved cards, no in-app checkout and no prepaid credit packages — which is common in sitting and is genuinely not supported yet. There are no credit notes, no deposits, and no accounting integrations. Creating an invoice needs a connection.
Questions walkers and sitters actually ask
Can I create monthly invoices?
Yes. At month end, run the whole book at once: every client with unbilled completed work gets an invoice built from that work, with the walks and visits as line items. You are not rebuilding the month from a calendar and a group chat.
Can I invoice work the app never saw?
Yes. A manual invoice covers a nail trim, a bag of food, a key cutting fee or work you did before you installed anything. It still takes a number from the same sequence, so there is no gap left by billing something outside the app.
Are invoice numbers sequential?
Yes, with your own prefix, issued centrally so two devices invoicing at the same moment cannot produce the same number or skip one. An empty invoice can never take a number, and a numbered invoice cannot be emptied afterwards.
Does it support VAT?
Yes. Set your VAT number and rate and it is applied and shown on the invoice; leave them blank and nothing about VAT appears. Your UTR, business address, logo, payment terms and invoice footer work the same way — shown when filled in.
Which currencies are supported?
Twenty-seven, including sterling, euro, US and Canadian dollars, Australian and New Zealand dollars, Swiss francs and the Nordic and Central European currencies. The currency is stamped onto each invoice when it is issued, so changing yours later never rewrites what a past invoice claims to have charged.
Can I record cash and bank-transfer payments?
Yes. Mark an invoice paid by cash, bank transfer, PayPal, card or anything else, with the date. Outstanding, overdue, paid and void are all tracked, so "who hasn't paid me" is one screen rather than an evening.
Can it chase overdue invoices for me?
Yes, if you switch it on — it is off by default. Nothing is sent before the due date, then at most three polite reminders at least a week apart, and then it stops and leaves it to you. Chasing someone nightly is how a walker loses a client and their neighbour.
Does CorePaw take a percentage of what my clients pay me?
No, and it never touches the money. The invoice is a document; your client pays you directly, into your account, by your link. There is no platform cut, no payout schedule and no third party sitting between you and your income.
Bill one run and time it.
Against however long the last one took you with a calendar and a calculator.
