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.

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.

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

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:
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.
Modules
Take only what you need. The rest can wait.
Invoicing comes with every plan. Switch on Finance, Construction or Accountant only when you need them — each is an add-on on top of your plan, with no new tools and no data migrations.
Your own VAT return (DDV-O) and bank statement import — keep your books straight without an accountant.

A proforma from the BOQ in one click

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

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

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.
