Invoice goes overdue, the cadence runs without you. Stop being the awkward one.

Card payments, no faff.
Stripe payment link on every invoice. Money lands in your bank, Hamar tracks the status.
Why we built this
You shouldn’t have to spend Sunday night chasing payment for last Thursday’s job.
Sole traders lose hours every week to admin that other software won’t do for them. Hamar handles the quoting, the invoice, the chase emails, and the receipts — so the only thing on your plate at the end of the day is the work you actually got paid for.
What’s in the box
Built for the way you actually work.
Saved line item templates + rate card import
Tag your usual jobs as templates and add them to a quote in one click. Already have a rate card in Excel? Paste it in or upload a CSV — Hamar imports the lot in one go.
Recurring invoice schedules
Monthly retainer, weekly hours, quarterly maintenance — set it once, Hamar generates the invoice on the right day every time.
Online accept on every quote
Send a public link, the client clicks Accept, you get an email with their name, IP, and timestamp on file. Convert to invoice with one click.
Stripe payments end to end
Connect Stripe, every invoice gets a Pay button. The money goes straight to your bank — Hamar doesn’t hold it. Card brands, Apple Pay, Google Pay all supported.
Auto-chase that keeps its dignity
Polite at day 7, firm at day 14, final at day 21. Per-invoice override if a client’s a friend. Cron runs daily so you don’t have to remember.
Your brand on every PDF
Upload your logo, set your accent colour, customise your invoice prefix. Quotes and invoices look like your company, not a template.
Client cards with full history
Every client has a page showing what they’ve quoted, invoiced, paid, and what’s outstanding. Plus internal-only notes for the next time you speak.
CSV export when you need it
Quotes, invoices, clients — all exportable. For your accountant, your spreadsheet, your peace of mind.
