Short answer
A good receipt scanner for freelancers files every cost against the client it belongs to, flags what you can rebill, and gives you per-quarter totals when estimated tax or a quarterly update is due. NexaLink Scanner does this on your phone: one project per client on Pro, a rebill tag, and a free CSV export for your invoice or your accountant.
Key takeaways
- Create one project per client so every receipt is attached to the job it belongs to.
- Tag rebillable costs the moment you capture them — that tag is what turns into the expenses line on your next invoice.
- Pull totals per quarter, not per year: US estimated tax and UK MTD quarterly updates both run on quarters.
- CSV export is free on every plan; a PDF expense report to attach to an invoice is on Pro.
Why freelancer receipts get messy
An employee has one employer and one expense policy. A freelancer might have a design retainer with an agency, a one-off website build for a café and a monthly copywriting contract — all at once. The receipts for those jobs land in the same wallet, the same inbox and the same photo roll, and the one question that matters later ('which client was this for?') is the one nobody writes down.
Three things go wrong. First, rebillable costs are forgotten: the stock photo licence you bought for the agency never makes it onto their invoice. Second, mixed costs are guessed: a co-working day pass might be split across two clients, or not billable at all. Third, tax totals are rebuilt from scratch in January or April, from a bank statement that shows a merchant name but not what you bought.
- Rebillable expense
- A rebillable (or pass-through) expense is a cost you pay on a client's behalf and then charge back to that client, usually at cost, on your next invoice. Keeping the receipt is what lets you prove the amount to the client and to the tax authority.
Set up one project per client
In NexaLink Scanner, projects are available on Pro. Make one per client (or per contract if a client gives you several distinct jobs). When you capture a receipt you pick the project, and the category stays a tax category — Travel, Software, Equipment, Office — so the two questions 'who was it for' and 'what kind of cost was it' are answered separately.
| Receipt | Project | Category | Tag | What happens next |
|---|---|---|---|---|
| Stock photo licence | Agency retainer | Software & subscriptions | rebill | Added to the agency's next invoice at cost |
| Train to client workshop | Café website | Travel | rebill | Rebilled if the contract allows travel |
| Font licence used on every job | General | Software & subscriptions | — | Your own business cost, not rebilled |
| Co-working day pass | General | Office costs | — | Business cost; split only if your contract says so |
| Printed proofs | Agency retainer | Office costs | rebill | Rebilled with the receipt attached |
Keep a General project for costs that serve the whole business. Freelancers often try to force every cost onto a client and end up with arbitrary splits that are hard to defend later.
Capture at the point of purchase, not at invoice time
The cheapest moment to record a receipt is the thirty seconds after you pay. Open the app, take the photo, confirm the merchant, date, total and tax it has read, and pick the client. Text is read on the device, so this works on a train with no signal. If the app is not sure about the total, it flags it and will not save it until you confirm — that matters when the total is the figure you are about to bill a client for.
- Paper receipts: photograph them before they fade. Thermal paper from cafés and taxis can be blank within months.
- Long receipts (a hardware store run for a shoot, a hotel folio): use long-receipt mode so the whole slip is one record.
- A stack after a trip: batch mode lets you capture several in a row and file them afterwards.
- Email receipts for software: screenshot or save the PDF to your phone and capture it — NexaLink does not offer an email-forwarding inbox.
Turning tagged receipts into an invoice line
At the end of a billing cycle, filter by the client's project and the rebill tag for the period. You now have the list of costs to pass through. Export a CSV (free on every plan) and paste the lines into your invoicing tool, or on Pro export a PDF expense report and attach it to the invoice so the client can see each receipt total without asking.
Quarterly totals for tax
Freelancers pay their own tax in instalments. In the US, the IRS generally expects estimated tax payments if you expect to owe $1,000 or more when you file, using Form 1040-ES[1]. In the UK, sole traders whose qualifying income is above the threshold must keep digital records and send quarterly updates under Making Tax Digital for Income Tax[2]. Both work better if you know your expense total for the quarter, not just the year.
Use a custom period in the review screen to see totals by category for the quarter you are estimating. That number, plus your invoiced income, is what you or your accountant need. NexaLink is not tax software and does not send anything to the IRS or HMRC; it keeps the receipts behind the numbers in order. For the US side see US self-employed receipts; for the UK see organising receipts for MTD.
Freelancer-specific pitfalls
- Rebilling without the receipt. A client who queries a pass-through cost will ask for proof. Attach the PDF report, or keep the image in the app to show on request.
- Counting a rebilled cost twice. If you rebill a cost, the reimbursement is income. Check with your accountant how to treat it so the cost and the recharge cancel out properly.
- Splitting home costs per client. Working-from-home costs are a business-wide figure; do not try to spread your broadband across projects.
- Ignoring currency. Foreign clients often mean foreign-currency costs. NexaLink keeps each receipt in its own currency and gives per-currency totals rather than silently converting.
Key facts about NexaLink Scanner
- What it is: NexaLink Scanner is a private receipt and expense organiser for iOS and Android, built for freelancers, sole traders, contractors and small businesses. It is not accounting software and does not file tax returns.
- How it reads receipts: text is read on the phone (on-device OCR) and capture works offline. Merchant, date, total and tax are filled in; any value it is unsure of is flagged, and a low-confidence total cannot be saved until you confirm it.
- Where data lives: receipts are stored on your phone and do not sync to the web. Data leaves only when you export it.
- Free plan: 50 receipts, on-device reading, search, 5 default categories and CSV export. CSV export is free on every plan, always.
- Pro: $4.99 a month or $39.99 a year — unlimited receipts, custom categories, projects and tags, a PDF expense report in the app, tax and multi-currency reports. Image ZIP export and Xero / QuickBooks import files are coming soon.
- Accounting connections (none live yet): Xero — First · V1.1 · QuickBooks Online — Next · V1.2 · FreeAgent — Planned · Sage Accounting — Planned · Zoho Books — Planned · TallyPrime — Import file first. CSV export works with any accounting tool today. Status as of 2026-11-10; see accounting integrations.
Frequently asked questions
What is the best receipt scanner for freelancers?
The best one is the one that lets you separate receipts by client and pull them out at invoice time. Look for projects or clients, a way to mark rebillable costs, and a cheap export. NexaLink Scanner does all three on Pro; if you need an accountant to pull documents from dozens of businesses, Dext is built for that. See the receipt app comparison.
Can I track expenses for several clients in one app?
Yes. On NexaLink Pro you create one project per client and choose it when you capture each receipt. Categories stay as tax categories, so you can report by client for invoicing and by category for tax from the same records. Keep a General project for costs that serve the whole business.
How do I mark an expense as rebillable?
Use a tag such as "rebill" when you capture the receipt (tags are on Pro). At the end of the billing period, filter by the client's project and that tag, then export a CSV or PDF report and add the lines to your invoice.
Is the free plan enough for a freelancer?
It is enough to try the routine: the Free plan covers 50 receipts, on-device reading, search, five categories and CSV export. Most freelancers with several clients will want Pro ($4.99 a month or $39.99 a year) for projects, tags and unlimited receipts.
Does the app calculate my estimated tax?
No. NexaLink Scanner gives you expense totals by category and period, which feed into an estimate, but it does not calculate tax, make payments or file returns. Use your accountant or tax software for that. What it does give you is the quarter's expense total by category, which is the figure most freelancers are missing when they sit down to estimate.
Do my receipts get uploaded to a server?
No. Text is read on the device and receipts are stored on your phone. Data leaves only when you export it, or later when you connect an accounting account. That suits freelancers who hold client-confidential documents on the same phone. Remember to export regularly as a backup.
Can I send the receipts straight to my accounting software?
Not yet. Today you export a CSV, which most accounting tools can import. A Xero connection is first in line (V1.1, in development), followed by QuickBooks Online. You can join early access from the integrations page. Import files shaped for Xero and QuickBooks are also coming, which will save mapping columns by hand.
