Issue in a minute

Send a polished invoice before your coffee goes cold.

Pick a client, add a line or two, hit send. Aries fills in the VAT, the running number and the UPN QR payment slip — you don't need to know a single accounting rule.

  • Invoice or offer in under a minute

    Start from a client or a catalog item and the document builds itself as you type.

  • Smart defaults, zero setup

    VAT 22%, due in 30 days, automatic numbering and a UPN QR slip on every PDF — change them only if you want to.

  • No accounting know-how needed

    Aries puts the right VAT clause and a valid number on the document, so it's correct the first time.

  • Repeat work in two clicks

    Duplicate your last invoice or copy one for a client, then just fix the date.

Free to start — no card, and your data is always exportable.

When invoices come in

You snap a photo. Aries reads and files it.

Snap a photo of a paper invoice on your phone, or drag in fifty PDFs at once. Supplier, amounts, dates and VAT fill themselves in — you just glance over it and confirm.

  1. 1

    Photograph or drag in

    On your phone, snap a photo of the invoice. At your desk, drag in PDFs — even 50 at once. Aries processes them in the background while you keep working.

  2. 2

    Aries reads

    Amounts, VAT, dates and line items fill in by themselves; the supplier is matched to your partner database.

  3. 3

    Confirm

    Check it, click, done. No retyping.

Hours of retyping a month become a few minutes of reviewing.

Data import

Switching tools isn't a migration. Your data comes with you.

Old software, Excel, a folder of PDFs — Aries digests it all. Upload the file, Aries detects the structure, you confirm. That's it.

Documents from Excel

Issued and received documents import with their partners — the columns are recognised automatically.

Articles from Excel

Upload a price list and your catalog builds itself — names, prices, units.

BOQ from Excel or PDF

Groups, sections, items — the structure survives down to the last code.

Resources & Services

Enter it once. Use it forever.

Most tools make you retype every line, every single time. We think that's madness.

Resources are your atomic cost inputs — an hour of labor, a unit of material, a machine rate. Services bundle them into what you actually sell, and Aries prices each service from its parts. No spreadsheets, no retyping.

  • A library instead of retyping

    Search, filter and drop resources and services into any document.

  • Prices built from real costs

    A service is a recipe: resources × quantities. Aries does the math, so the price is always built from your actual costs.

  • A proforma in seconds

    Client, two services, send. PDF, numbering, VAT and totals are handled.

Documents

All eight document types. No retyping in between.

An offer becomes an invoice in one click and the data carries over by itself. The order? Yours. We don't force one.

One click turns a document into the next:

Offer
Proforma
Invoice
Work order
Invoice
Progress claim
Invoice

Duplicate your last document and just fix the date

Sending documents

Aries writes the email for you. You just hit send.

When you send an invoice or an offer, Aries drafts the whole message from the document — recipient, subject and text. You can edit anything before it goes out, and it's sent straight from the app, in your company's name.

  • The message writes itself

    Document type, number, amount and due date become a polite message — no typing.

  • Edit anything before sending

    The draft is a suggestion, not a command: tweak it, add to it or replace it.

  • Sent straight from the app

    No copying into Gmail or Outlook. Sent in your company's name; replies land in your inbox.

Automation

The best click is the one you don't make.

VAT without guessing

22%, 9.5%, exemptions and reverse charge (76.a) — the correct rate and clause land on the document by themselves, every time.

Recurring invoices

Set a monthly invoice up once. Aries then issues it by itself — every month, even when you're on vacation.

Automatic partner matching

When reading or importing documents, Aries matches the supplier to your database — tax ID included.

Documents in 6 languages

Issue any document in Slovenian, English, German, Croatian, Italian or Serbian.

Foreign invoices, converted

Received invoices in a foreign currency convert to EUR automatically, using daily European Central Bank rates.

The basics, covered

And every obvious thing, done right.

The essentials a Slovenian business expects — already here, no setup, no add-on.

  • UPN QR on every invoice

    A scan-to-pay slip on the PDF, exactly to the Slovenian standard.

  • Company lookup by tax ID

    Type a tax number and the name, address and VAT status fill from the business register.

  • Dashboard & overdue at a glance

    Revenue, what's due and what's overdue — the moment you log in.

  • One-click payment reminders

    Chase an unpaid invoice with a ready-written reminder.

  • Documents in 6 languages

    Slovenian, English, German, Croatian, Italian, Serbian.

  • Your data, always exportable

    Every document and partner out as PDF or CSV, anytime.

Construction module

From BOQ to progress claim to invoice. No Excel in between.

A construction module everyone on site understands: create or import a BOQ, issue progress claims with cumulative tracking, and always see whether the project is making money — or eating it.

  • A BOQ in minutes

    Build it from your own items or import an existing Excel or PDF — the structure is preserved.

  • A proforma from the BOQ in one click

    One click turns a BOQ into a proforma or an offer — items and amounts carry over by themselves.

  • Progress claims with cumulative tracking

    S1, S2, S3 … quantities are tracked cumulatively against the BOQ, and the recap is always up to date.

  • Invoice from a progress claim

    One click turns an approved progress claim into an invoice. No copying numbers by hand.

  • Costs per project

    Attach received invoices to a project and instantly see whether you're still within budget.

Why Aries

Nobody started a business for the paperwork.

Tools should work for you — not the other way around.

So we built Aries.

Aries was born out of our own frustration. The tools we used were slow and overloaded — a manual for every step, too many clicks for every invoice. So we built the app we wished we had: simple, fast, no bloat.

For freelancers, small businesses and construction companies. Fewer clicks, less retyping, more time for real work. And this is just the beginning — Aries learns something new every month.
