Client work gets messy when every step lives in a different tool

Proposals in one app. Contracts in another. Invoices in a spreadsheet. Payment reminders in your memory. InvoiceBirds brings the workflow back into one place.

Scattered documents
Proposals, contracts, and invoices live in different files, so you retype the same client details every time.
Late payments
Unpaid invoices are easy to miss when reminders and follow-ups are manual.
Waiting on signatures
Work starts late while a proposal sits unanswered or a contract waits in someone's inbox.
PDFs are being phased out
Clients now ask for e-invoices like ZUGFeRD and XRechnung, and Germany requires them for VAT-registered businesses from 2027 and 2028.

Connected invoicing workflow

Connected invoicing software for client work

InvoiceBirds helps consultants, studios, and service businesses create client documents, get paid by card, chase overdue invoices, and keep expenses and tax reports in one clean workspace.

Create client documents faster

Build proposals, estimates, contracts, and invoices from the same client details, so you do not repeat the same information every time.

Proposals, estimates, contracts, and invoices in one list
Track payments and collections

Accept Stripe payments, see which invoices are paid or overdue, send reminders, and follow up before unpaid invoices affect your cash flow.

Payment overview: paid, overdue, and due soon
Organize expenses and tax reports

Track expenses, tax collected, estimated tax owed, and net income so your business records stay organized before tax season.

Revenue, tax collected, expenses, and net after tax
One connected workflow

From first quote to final payment

One record carries the client from the first quote to the paid invoice, so nothing is typed twice and nothing slips.

ProposalPrice the work and share it.
EstimateGive clients a clear quote.
ContractAgree on scope and terms.
InvoiceCreated from the contract, no retyping.
PaidClient pays by card from the invoice.
RemindersLate payers are chased for you.

Connected cash flow

Every client. Every payment. One clear record.

No more jumping between Google Docs, an e-signature tool, a spreadsheet, and your inbox.

Win and confirm the work

Know the moment your client says yes

Send a proposal or estimate as a link. Your client accepts it, signs the contract on their phone, and you are notified each time, with a one-click button to create the next document.

Proposals
See when it is opened and accepted, then create the contract from the email.
Estimates
Clients approve from a link, and it becomes an invoice in one click.
Contracts
Clients draw their signature online, on phone or desktop.
Nothing typed twice
Client, scope, and pricing carry over from proposal to contract to invoice.

Bill and collect

Get paid from the invoice. Let reminders chase the rest

Your client pays by card straight from the invoice and it marks itself paid. The ones who forget get a reminder, in the tone you choose.

Paid from the invoice

Card payments through Stripe go straight to your account, and the invoice updates to Paid on its own.

Automatic reminders

Before, on, and after the due date, in a friendly, professional, firm, or final tone.

Overdue worklist

See who is late, by how much, and which clients tend to pay late.

Invoice by voice

Say "Invoice Acme 3 hours at 120, due in 14 days" and get a ready draft.

Understand your business numbers

Track the financial side of your business with reports that help you understand performance without turning InvoiceBirds into accounting software.

Tax Reports

Track revenue, tax collected, estimated tax owed, and net after tax.

Flexible tax setup

Expense Profiles

EU e-invoicing, built in

Send e-invoices your clients can accept. Read the ones you receive.

Germany requires VAT-registered businesses to issue e-invoices from 2027 and 2028. InvoiceBirds turns the invoice you already made into a compliant ZUGFeRD or XRechnung file you can email, and opens the XML invoices your suppliers send you.

Send real e-invoices
Export any invoice as Factur-X / ZUGFeRD (EN 16931), XRechnung 3.0, or Peppol UBL. Included on every plan, Free too.
Checked before you send
A readiness check flags what is missing, client VAT numbers are verified in the EU VIES register, and reverse charge is applied for cross-border EU clients.
Read any e-invoice
Got an XML invoice you cannot open? Drop in the XML or Factur-X PDF and see the supplier, VAT numbers, invoice number, dates, and totals.
One inbox for supplier invoices
Every e-invoice you receive is stored, its format recognized automatically, and easy to find again.

The frustration

"My country uses VAT not a generic Tax label."

How InvoiceBirds solves it

Rename tax labels to VAT, GST, Sales Tax, MWST, or terminology that matches your business.

No with other tools

Tax labels are commonly fixed and cannot be renamed.

The frustration

"My invoices look generic and do not represent my brand."

How InvoiceBirds solves it

Customize your branding, colors, document details, fields, notes, templates, and client-ready PDFs.

Limited with other tools

Customization is usually restricted to a logo and one accent color.

The frustration

"I use separate tools for estimates, proposals, contracts, and invoices."

How InvoiceBirds solves it

Create and manage every client document inside one connected workspace.

No with other tools

Proposals, contracts, and invoices are often disconnected or require separate tools.

The frustration

"My client asked for an e-invoice, not a PDF."

How InvoiceBirds solves it

Export any invoice as ZUGFeRD / Factur-X, XRechnung, or Peppol UBL, on every plan, and open the e-invoices your suppliers send you.

Limited with other tools

Many invoicing tools still only produce PDFs, or charge extra for e-invoice formats.

The frustration

"I am charged more when my business creates more invoices."

How InvoiceBirds solves it

Invoices are unlimited on every plan, including Free.

No with other tools

Some tools restrict the number of invoices, clients, or documents you can create each month.

The frustration

"I waste time manually chasing clients for unpaid invoices."

How InvoiceBirds solves it

Send automatic reminders before, on, and after the due date, and see which invoices are paid, sent, or overdue.

Limited with other tools

Reminders may be manual or restricted to more expensive plans.

The frustration

"I cannot easily turn approved work into an invoice."

How InvoiceBirds solves it

Move from estimate or proposal to contract, invoice, and payment without recreating information.

No with other tools

Documents must often be created separately and updated manually.

The frustration

"I do not want limits, surprise upgrades, or extra costs just because my business is growing."

How InvoiceBirds solves it

Flat monthly pricing with no per-seat or per-document fees.

Limited with other tools

Pricing often scales with document volume or seats.

The frustration

"I cannot clearly see my revenue, expenses, payments, and taxes."

How InvoiceBirds solves it

Manage revenue, expenses, collections, payment activity, and tax reports in one view.

No with other tools

Financial data is usually split across separate tools and exports.

The frustration

"I work with clients in different countries and tax systems."

How InvoiceBirds solves it

Invoice in 66 currencies, check EU VAT numbers, and apply reverse charge for cross-border EU clients.

Limited with other tools

Multi-currency and regional tax support is often limited.

The frustration

"I manage different businesses or expense categories."

How InvoiceBirds solves it

Use multiple expense profiles and keep financial records properly organized.

No with other tools

Separate businesses usually require separate accounts.
