Why link a payment to an invoice
When you make out an invoice, Worklog already counts that money as income on the day you issue it. So when the customer actually pays and you log the money coming in, you need to tell Worklog it is for that same invoice. If you do not, the amount gets counted twice and your Profit and Loss looks bigger than it really is.
Linking fixes that. It keeps the payment out of your Profit and Loss, so the invoice you already logged stays the only place that money is counted. You can also tick a box to mark the invoice as paid at the same time.
Before you start
- The invoice needs to exist already, so there is something to link to.
- You link the payment when you log the money coming in, not on the invoice itself.
Link a payment as you log money in
This is the everyday way, for when a customer pays you and you record the money by hand in Banking → + Add.
- Open Banking, tap + Add, and on the line tap 💰 In.
- Type who paid in the first box, and the Amount that came in. Type the customer's name as it is on their invoices and Worklog puts their invoices first.
- Under the line, find the box labelled 'Is this payment for an invoice?' and tap it. It shows once there is an amount and an invoice still owed.
- A list opens. If you named the customer, their invoices show first under their name, with the rest below. Tap the invoice this payment is for. You can also use the 'Search by customer, number or amount' box to find it. If the first box was empty, picking the invoice fills in the customer's name.
- A blue note appears: '✅ Linked to [invoice number] — its income and its VAT are already counted on the invoice, so this payment isn't counted twice.' That is your confirmation.
- Tap Done, then ✅ Save all lines.
Mark the invoice paid at the same time
If the payment covers the full outstanding balance, Worklog offers to close the invoice off for you. When you pick an invoice, this box is ticked for you already.
- After you link the invoice, a tickbox appears saying 'This covers the full [amount] balance — mark [invoice number] as paid'.
- Leave it ticked to mark the invoice paid when you save, or tap it to untick it and leave the invoice open.
- Tap ✅ Save all lines. The payment is saved and, if you left the box ticked, the invoice is set to Paid.
Linking payments from an imported bank statement
When you import a bank statement, Worklog reads every transaction and lets you link deposits to invoices before anything is saved. This is handy when several customers have paid and you want to match them all at once.
- Open Banking, tap "Let Worklog read it", and follow the steps to upload and read your statement.
- On the review screen you see every transaction Worklog found, each with a tick so you choose which ones to keep.
- If you have invoices on file, a note shows: 'Was a payment settling an invoice or supplier invoice you already logged? Link it below so the same money isn't counted twice in Profit & Loss.'
- Under a money-in row you keep ticked, tap the 'Is this payment for an invoice?' box and pick the invoice it settles, the same as on Capture bank lines.
- If the deposit covers the full balance, the same mark-as-paid tick appears for that row. Leave it ticked to close the invoice off.
- When you are happy, tap the Import button at the bottom to save everything.
A note on VAT
If you are VAT registered, the cash you log is treated as VAT-inclusive and Worklog works the VAT out of it for you. A line that isn't linked shows its VAT beside More — Standard, for a normal sale. Once you link an invoice, it reads On invoice instead, and the matcher's note says the VAT and income for the sale already live on the invoice. Linking is what keeps both your income and your VAT from being counted twice.
What the match actually does
The invoice already carries the revenue — and, for a VAT-registered business, the VAT — from the moment it was issued. So the matched payment deliberately contributes neither: it settles the document without counting the same money twice, which is why a matched payment stores no category of its own.
A payment smaller than the balance comes off what the invoice says is owed and leaves it open for the rest; the full amount, with the tick left on, flips it to paid.
If the invoice isn't in the list
- Only invoices still owing money are offered. For an invoice that shows as paid with no money logged, open it and use the amber note's 💰 Log the amount, or Already logged it? Link it. If you edit a payment that a paid invoice stands on and take the link off, link another invoice or lower the amount, Worklog warns that the invoice will show as owing again — and a paid invoice can't be put back to paid without the money.
- A fully credited invoice has nothing left to settle, so it isn't offered either.
- The one exception: the invoice this payment is already matched to always stays visible, so an old link can be changed or cleared.
