Invoicing Software for Small Business
Refrens is online invoicing software for small businesses, freelancers and service firms. It handles the whole money cycle: quote, invoice, online payment, reminders and books.
Most invoicing tools stop once the invoice is sent. Refrens keeps going. It chases the payment on WhatsApp and email, shows you when a client opens the invoice and lets your whole team work in one live account. An AI assistant on WhatsApp handles the rest.
Built for people who sell skills and projects: consultants, agencies, engineers, creators, professional practices and field service crews. Bill clients in the US, UK, Australia, Canada, Africa or any of 170+ countries, in 150+ currencies.
Businesses that use Refrens for invoicing
Slow invoicing costs you time and cash
Every invoice costs you twice. First, the time it takes to make and send. Second, the days you wait to get paid. Both come out of your week, and both are avoidable.
Wherever you start, the same gaps show up
Pick where you are today.
Word or Excel templates
Templates look fine. They remember nothing. You retype the client and the items every time. You cannot see whether the client opened the file. Nobody reminds the client, so you do.
A spreadsheet
A spreadsheet stores numbers. It does not send, track or remind. One moved cell breaks a total. Last month's file becomes this month's invoice, with last month's mistakes.
Other invoicing software
Many tools are built around the accountant's workflow: ledgers, journals and bookkeeping screens. You wanted to send an invoice and get paid. You got a system to learn first. If that is why you left, this is the difference.
New and have never used anything
Refrens can be your first software. You do not need accounting knowledge. Add your business, add a client and send an invoice. Add the rest when you need it.
What changes with Refrens invoicing software
Speed.Pick a saved client and saved items. Send the invoice in one click, on WhatsApp, by email or as a link.
Easy to use.The screens follow your day: create, send, track, get paid. Accounting sits there when you want it, and your accountant joins when you invite them.
Time saved.Saved clients, saved items, recurring invoices and quote to invoice in one click remove the retyping.
Follow-up.See which invoices are open, which are late and which clients to chase first.
Reminders.Reminders go out on schedule by WhatsApp and email, before and after the due date. You stop sending them by hand.
Tracking.See when a client views, accepts or pays an invoice. Templates and spreadsheets cannot show you that.
Refrens is built for the person who sends the invoice and waits for the money.

AI invoicing software that does the admin
Stop typing. Start forwarding. Refrens invoicing software reads your bills, creates invoices from a WhatsApp message and answers questions from your live data.
Refrens Eagle: bill capture from WhatsApp and email
Forward a vendor invoice, purchase bill or expense receipt to Refrens Eagle on WhatsApp. Or let approved vendors email it to your dedicated Refrens address. Eagle extracts the vendor, invoice number, date, tax, amount and line items. It matches the bill to an existing vendor and prepares a Purchase or Expense draft.
Only approved WhatsApp numbers and allow-listed email senders can submit documents. Nothing reaches your books until your team reviews and saves it.
Refrens AI on WhatsApp
Chat with Refrens on WhatsApp. Create quotations and invoices. Record payments against invoices. Add leads. Check overdue invoices and low stock. Ask for a morning digest of receivables, payments received, upcoming dues and inventory alerts. You never log in to Refrens.
Connect your account once. Choose exactly which permissions the assistant gets. Permissions that delete data stay off unless you turn them on.
Example (illustrative): A plumber types "invoice Dana $480 for the boiler repair" between jobs. He checks his overdue list the same way.
AI-powered OCR for vendor bills and receipts
Upload a vendor invoice, bill, receipt or handwritten note as a PDF or photo. Refrens extracts the vendor name, invoice number, date, tax amount and line items at 99% accuracy for your review and approval. Bulk OCR processes a full month of bills in one upload and queues them for bulk or individual approval. That cuts processing time from an hour to minutes.
Ask Freya and connect ChatGPT or Claude
Ask Freya, the Refrens AI assistant, about receivables, outstanding payments, sales performance and customer activity. It answers from your live data. Refrens MCP also lets you manage invoices and payments from ChatGPT or Claude.

Inventory and invoice software that moves your stock for you
You sell items, not hours. Every invoice should change your stock, and every purchase should add to it. When invoices and stock live in two places, one of them is always wrong.
Refrens keeps them together. You invoice a customer, and the stock drops. You receive goods from a vendor, and the stock rises. You see what you have, where it is and what to reorder.
Stock updates itself Illustrative
Stock updates itself
What it does: Updates stock with every purchase and every sale. Tracks quantities and movements in real time.
Strict inventory control
What it does: Prevents negative stock across items, warehouses, batches and packages. You do not sell or dispatch more than you hold.
Multiple units of measurement
What it does: Lets you buy in one unit and sell in another. You set a base unit and conversion rules. Stock stays accurate in the base unit.
Multi-location stock and transfers
What it does: Manages stock across branches and warehouses from one dashboard. Moves stock between locations with delivery notes.
Stock alerts and reorder levels
What it does: Alerts you when an item falls below its reorder level or sits above its overstock level. Creates a purchase order from a low-stock item.
Batch, serial and expiry tracking
What it does: Tracks goods by batch or serial number. Records expiry dates and warranty periods.
Package items
What it does: Bundles items you sell together. Stock for each part drops when you sell the bundle.
Quote to order to invoice, in parts
What it does: Converts a quote or order into invoices in parts. Tracks billed, fulfilled and pending quantity for each item.
Product-wise profitability
What it does: Records buying price, landed cost and selling price. Shows margin per product.
Bulk stock adjustment
What it does: Updates stock quantities in bulk from a CSV file.
Inventory reports
What it does: Shows stock valuation, expiry, stock status, movement and party-wise transactions. A separate report lists unsold inventory, its value, its location and the days without a sale. You can save custom report views with filters.
Check stock from WhatsApp
What it does: Ask Refrens AI on WhatsApp for low-stock items and a morning digest of inventory alerts.
A week in the life of a distributor
Where Refrens inventory stops
Refrens does not manage production or bills of materials.
Refrens is not a point-of-sale system for a retail counter.
For heavier stock work, read about warehouse invoicing software. It goes deeper on wholesale and distribution.
Invoicing software built for service businesses and professionals
Refrens fits businesses that sell time, skill and projects. You bill in stages, you send quotes first and you wait on clients to pay.
1. Consultants, agencies and engineering firms
Professions: consulting, digital marketing, social media, IT services, web development, architecture, engineering firms, professional services.
Why it fits: You sell retainers and projects. You bill clients in several currencies. Your clients' accounts teams want a PO number and proof you sent it.
Features you will use: recurring invoices, installments, customer PO number, custom fields (project codes), approval workflows, multi-currency, reminders.
What you can do: Bill a $4,000 retainer on autopilot. Split a $20,000 build into four milestones. Require partner approval on invoices above a set value.
Example (illustrative): An engineering consultancy bills three clients on retainers and one on milestones. Recurring invoices cover three. A four-step schedule covers the fourth. Project codes sort every report.

- Consulting: milestone invoices and a PO line.
- Digital marketing: retainer plus ad spend as a separate line.
- Social media: package pricing with recurring invoices.
- IT services: retainers, project phases, PO numbers.

What you can do: Take a 30% deposit, deduct it on the final invoice and add a late fee line if the client slips.

By profession

- Photography: deposit then balance.
- Videography: deposit, balance and an add-on line for extra edits.
3. Licensed and professional practices

Features you will use: saved clients, payment receipts, installments, client statements, roles for your front desk and accountant.
What you can do: Bill itemized services, take part payments and issue a receipt for each.
Example (illustrative): An interior designer bills $9,000 in three stages: $3,000 on approval, $3,000 on delivery, $3,000 on handover.
By profession
- Law firm: itemized fees and retainer deductions.
- Tax: fixed-fee engagements and recurring monthly bookkeeping.

- Interior design: staged payments tied to project phases.
4. Field and project services
Professions: plumbing, handyman, roofing, landscaping, auto repair, towing, trucking, rental, DJ, catering, travel agency.
Why it fits: You bill per job. You collect deposits. You invoice from a phone.
Features you will use: advance as a deduction, installments, payment receipts, reminders, recurring invoices for rentals and contracts.
What you can do: Take a deposit, finish the job, invoice the balance and send a receipt.
Example (illustrative): A roofing contractor quotes $8,500, takes a $2,500 deposit and invoices the $6,000 balance after the work.
By profession
- Plumbing and handyman: job invoices from the site.
- Roofing: deposit, then balance at completion.

- Auto repair: parts and labor on separate lines.
- Towing and trucking: per-trip items and saved client accounts.
- Rental: recurring invoices for property, equipment and vehicle rent.

Also works for: catering, travel agency and trucking sit outside our core focus. They work for simple invoicing. For route planning or dispatch, pair Refrens with a specialist tool.
5. Wholesale and trading businesses
Professions: wholesale, distribution, trading.
Why it fits: You bill by the item, ship against orders and need stock to move when you invoice.
Features you will use: quote to invoice, order conversion, delivery notes, purchase orders, inventory updates.
What you can do: Convert a quote to an order, ship in parts and invoice what shipped.
Example (illustrative): A trader quotes 500 units, ships 300 now and 200 next week. Each shipment becomes its own invoice.
See the full inventory feature set above, and go deeper on warehouse invoicing software.
Online invoicing software for your trade, wherever you bill from

Invoicing software for small businesses in the US, UK, Australia, Canada and Africa
Refrens bills in 150+ currencies and serves businesses in 170+ countries. Set your currency and business details once. Every invoice uses them.
Be honest before you sign up
Refrens is not the right fit if you:
Run a retail counter or shop.
You need point-of-sale and retail invoicing software with barcode scanning.
Manufacture goods.
Production planning and bills of materials are outside what we do.
Run a restaurant, hotel or D2C store.
Order flow and storefront tools fit better.
Need timesheets that turn into invoices.
Refrens has no timesheets. Hourly billers enter hours as line items.
Need a client portal with its own login area.
Refrens has none. Your client accepts or rejects a quote or invoice online, and creates a Refrens account to do it.
Need a desktop app.
Refrens runs in the browser, plus Android and iOS apps.
Why Refrens invoicing is better than a spreadsheet
A spreadsheet files data. It does not chase money.
Spreadsheets still work for a handful of invoices a year. After that, the hours add up.
Why Refrens invoicing is better than other software in the market
Invoicing apps look alike on the surface. The difference shows up in the work around the invoice. Here is what Refrens puts in one account.
Where Refrens is not the first choice
We say it plainly:
You need built-in timesheets.
You need a separate client login portal.
You run a retail counter or a factory.
If those are your core need, pick a tool built for them. If you bill clients for skills and projects, Refrens fits.
