Late payment is usually a process problem
Customers rarely refuse to pay. They forget, the invoice slips down an inbox, and nobody chases because chasing is uncomfortable and easy to postpone. Fixing that is mostly a matter of the follow-up happening reliably, whether or not anyone remembers.
A minute to raise, not an evening
Saved customers, a live product catalogue and your own tax settings mean an invoice is three fields and a send. Recurring work goes out on a schedule without you touching it.
Follow-up without the awkward call
Reminders go out on the schedule you set, in wording you approve, and stop the moment the invoice is settled. Nobody has to decide whether today is the day to chase.
Settled means settled
Each invoice carries its own account number, so the payment arrives already attached to it. Part payments reduce the balance, and the invoice closes itself at zero.
From blank screen to sent, in four steps
Pick the customer
Choose an existing customer or add one as you go. Their address, tax details and payment history come with them.
Add the lines
Pull items from your catalogue with prices already set, or type a one-off line. VAT and withholding tax are applied by rule, not by memory.
Send it where they read
Email, SMS or a link you paste into a chat. The invoice opens as a page they can pay from, so there is no attachment to lose.
Let it settle itself
Reminders run on schedule, the payment posts against the invoice, and the customer statement updates without a manual entry.
An invoice in under a minute, and it can pay itself
Saved customers, a live catalogue and your own tax rules mean an invoice is a few fields and a send. It goes out with its own account number printed on it, so the customer transfers to a number that belongs to that invoice and nothing else.
- Lines pulled from your catalogue at current prices
- VAT and withholding tax applied by rule
- Its own account number, so the payment matches itself

The chasing that nobody wants to do, done quietly
Late payment is rarely refusal. It is usually an invoice that slipped down someone's inbox. A short, polite sequence recovers most of it, but only if it actually goes out every time, which is exactly the thing a busy week destroys.
- Set the schedule once, per customer or per invoice
- Reminders stop automatically when payment lands
- Escalate to a colleague only when it is genuinely overdue

Know what you are owed without building a report
Open, part paid, due this week, overdue past thirty days. The ageing you would normally rebuild in a spreadsheet is a live view, because it is drawn from the invoices themselves rather than a copy of them.
- Aged receivables by customer, without a manual roll-up
- Statements of account a customer can be sent directly
- Credit notes and write-offs recorded against the original

What changes when invoicing lives in the system
The usual way
- An invoice template that lives on one laptop
- Numbering that breaks the moment two people raise one
- Reminders that depend on someone remembering
- A separate spreadsheet to work out who still owes what
- Payments identified by reading transfer narrations
With Niimbu
- One invoice list the whole team works from
- Sequential numbering the system owns
- A reminder schedule that runs whether or not anyone is watching
- Ageing and statements drawn from live invoices
- Payments matched on arrival by the invoice's own account number
The invoicing detail that real billing needs
No add-on modules and no higher tier to unlock the basics. These are part of invoicing from the first day you open an account.
Recurring invoices
Retainers and subscriptions issue themselves weekly, monthly or on your own cycle.
Quotes and proforma
Send a quote, convert it to an invoice on acceptance, and keep both linked.
Part payments
Deposits and instalments reduce the balance and keep the invoice open until it clears.
VAT and withholding tax
Applied by rule per line, shown clearly on the document and carried into your records.
Foreign currency
Invoice in USD, GBP or EUR, with the rate used stored on the transaction.
Your branding
Logo, colours, payment terms and footer notes, set once and applied to everything you send.
Credit notes
Issue a credit against an invoice and keep the audit trail intact rather than editing history.
Statements of account
One document showing everything a customer owes across invoices, ready to send.
Delivery notes and receipts
Generate the paperwork a trade customer asks for from the same record.
Late payment is a process problem, not a relationship problem.
Most customers are not refusing to pay. The invoice slipped down an inbox and nobody followed up, because following up is uncomfortable and easy to postpone. Once the follow-up is automatic, it simply happens.
Billing looks different in every trade
Retainers, term fees, stage payments and trade terms are not the same job. Pick the closest fit.
Professional services
Bill by project, milestone or retainer, and stop losing billable hours to collection.
Distribution and wholesale
Trade customers on terms, with statements and ageing that hold up in a payment conversation.
Schools and education
Term invoices per pupil, part payments tracked, and a clear view of who has settled.
Construction and contracting
Stage invoices against a project, with retention and variations recorded on the same job.
Freelancers and sole traders
Professional documents without a template, and follow-up that does not feel personal.

Frequently asked questions
How do I create and send an invoice?
Choose the customer, add lines from your catalogue or type them, then send. Niimbu applies your tax rules, numbering and branding automatically. The invoice goes out by email, SMS or as a link you can paste into a chat, and it opens as a page the customer can pay from directly.
Can I set up recurring invoices?
Yes. Any invoice can be set to repeat weekly, monthly, quarterly or on a custom cycle, with an optional end date. Recurring invoices carry their own reminder schedule, so a retainer client is billed and followed up without anyone raising it each period.
How does a payment get matched to the right invoice?
Every invoice is issued with its own account number. When the customer transfers to that number, the payment arrives already tied to the invoice and posts against it, usually within seconds. Nobody has to read a transfer narration or guess from the amount.
Can a customer pay an invoice in instalments?
Yes. Part payments reduce the outstanding balance and the invoice stays open until it reaches zero, at which point it closes and the reminder schedule stops. The full payment history stays visible on the invoice.
Does Niimbu handle VAT and withholding tax?
Yes. VAT is applied per line by rule and shown clearly on the document. Where a customer deducts withholding tax, the deduction is recorded against the invoice so the balance reflects what will actually be received and your records show both figures.
Can I invoice a customer in a foreign currency?
Yes. Invoices can be issued in USD, GBP or EUR for customers paying from outside the country. The rate applied is stored on the transaction, so the local-currency value in your books is traceable rather than reconstructed later.
What happens to an invoice in my books once it is paid?
The payment posts against the invoice, the customer's balance and statement update, and the entry flows through to bookkeeping without a separate journal. That is the advantage of invoicing sitting inside the same system as the rest of your records rather than being integrated with it.
Is there a limit on how many invoices I can send?
No. There is no cap on invoices and no per-user charge, so a growing sales team does not change what you pay. Charges apply to money moving, not to documents raised.
The rest of Get Paid
Collection works best when the channels share one set of records. Each of these feeds the same customer, invoice and account history.
