Selling cookies from your kitchen, abayas from Instagram, or repair services from your phone — the receipt your customer needs to see isn't a thermal slip. It's a clean A4 PDF, with your logo, the items, the total, and your contact info. Something they can save, forward to their accountant, or print if needed.
Most POS apps were built for shopfronts and forgot about this. QuickBiz didn't.
How invoicing works in QuickBiz
Every sale you record in QuickBiz is automatically an invoice. There's no separate "invoice flow" — the same Add Sale screen that updates your inventory and profit also produces a shareable document.
At the end of a sale, you get two output options:
- Thermal receipt — 58mm or 80mm paper, printed via Bluetooth or LAN thermal printer. For in-shop counter sales.
- A4 PDF invoice — full-page invoice with your logo, business info, line items, totals, and payment status. Generated on the fly.
Tap "Share" on a sale and your phone's native share sheet opens — pick WhatsApp, Telegram, Email, Files, or any other app. The PDF goes directly to the customer in seconds.
What's on a QuickBiz invoice
Every A4 invoice includes:
- Your shop branding — logo, business name (Arabic + English if both set), tax ID, civil ID, address, phone, email
- Invoice number — sequential, auto-generated, used for accounting reference
- Invoice date and due date (if it's a credit sale)
- Bill-to customer — name, phone, address (whichever fields you've recorded)
- Line items — product name, quantity, unit price, line total — with optional descriptions
- Subtotal, discount, tax, grand total (in KWD, 3-decimal precision)
- Payment breakdown — Cash / Online / Credit / Partial split if the sale was multi-payment
- Payment status — Paid / Partial / Credit
- Footer message — your custom closing line and terms
The invoice is professional enough for B2B sales, formal enough for government tenders, and clean enough for a customer to forward to their accountant.
Use cases where invoicing matters most
Home bakers and cottage food businesses
You took a wedding cake order for 250 KD. The customer paid 100 KD as deposit and owes 150 KD on pickup. After confirming the order, you send a partial-payment invoice via WhatsApp. They reply "received." Two weeks later when the cake is ready, they pay the balance and you send the final paid invoice. Clean paper trail, professional appearance, no awkward "how much was the deposit again?"
Online boutiques (Instagram, WhatsApp sales)
You sell abayas from Instagram. A customer DMs to order three. You record the sale in QuickBiz, send the invoice through WhatsApp, customer transfers the payment to your account, you mark it as paid and ship. The invoice is the agreement, the receipt, and the proof of delivery in one document.
Repair shops and service businesses
Phone repair, AC servicing, computer fix, tailoring — any service where the customer wants a written quote before approving the work. Record the sale with a "Credit" payment status (so it shows as not-yet-paid), share the invoice, and update the status when paid.
B2B sales to other businesses
You sell to other small shops who need a formal invoice for their bookkeeping. QuickBiz's A4 invoice has all the fields their accountant needs: your tax ID, theirs (if recorded), line items, tax breakdown.
Sending an invoice — step by step
- Record the sale in QuickBiz — Add Sale, products, customer, payment category
- Tap Share on the sale confirmation screen
- Choose A4 PDF (or thermal receipt if you prefer)
- Your phone's share sheet opens — pick WhatsApp, Email, Telegram, or any other channel
- Select the customer in the chosen app and send
Total time: about 15 seconds after the sale is recorded. Much faster than retyping an invoice into a separate app.
Arabic, English, and bilingual invoices
QuickBiz can generate invoices in any of three formats:
- Arabic only — for customers who prefer Arabic. Full RTL layout, all labels in Arabic.
- English only — for customers who prefer English or for B2B with non-Arabic-speaking partners.
- Bilingual — Arabic + English on the same invoice. Most professional-looking option for B2B in Kuwait.
You can set the default in Settings → Print Settings, or override per-customer on their customer record. QuickBiz picks the right format automatically when you share.
Reprint or resend a past invoice
Customers lose invoices. Accountants lose invoices. Your phone storage might lose them too if you forgot to back up. QuickBiz keeps every sale forever, with its associated invoice generatable on demand. Open the sale, tap Share, get the PDF again. No "let me check my notebook" delay.
What QuickBiz does NOT do (yet)
Honest about limits:
- No recurring invoices yet — you can't set up "send this invoice every month." If you bill the same customer the same amount monthly, you record each sale manually. (On our roadmap.)
- No customer-self-service invoice portal — customers can't log in to see their invoice history. They get the PDF you send them.
- No automatic payment reminders — QuickBiz doesn't email "your invoice is overdue" — you manage that conversation directly with the customer. (We see this less as a missing feature and more as a respect-the-relationship choice for small businesses.)
