About
Side Streams is invoicing for people with more than one income: the rental flat, the weekend bakery, the consulting on the side. Keep each side business as its own stream, with its own customers, invoice numbers and banking details, and see exactly what each one earns.
INVOICES THAT LOOK PROFESSIONAL
• Tax invoices with your logo, address and bank details
• Sequential numbering per stream: INV-000001, INV-000002…
• Line items with quantities, units and optional VAT
• Share the PDF by WhatsApp, Mail, Messages or AirDrop
• Draft, Sent, Partially paid, Paid and Overdue at a glance
PAYMENTS AND EXPENSES
• Record full or part payments: EFT, cash, card, SnapScan, Zapper, PayShap
• Snap a receipt with the camera or attach a PDF
• Expense categories for each stream
REPORTS FOR THE SA TAX YEAR
• Income, expenses and profit per stream, March to February
• Month-by-month breakdown and who still owes you
• Export to CSV for your accountant
SHARE WITH YOUR PARTNER
• Share a single stream with your partner or accountant through iCloud
