For small and medium business

Website, online store, accounting and suppliers — one system

You take care of marketing and sales; we build and run the systems — your website or online store, its link to accounting and your supplier price lists — and set up SEO and your ad accounts.

Why one system

When everything is connected, nothing gets retyped

The usual setup

  • A theme and many plugins from different authors, whose updates know nothing about each other.
  • Invoices issued in the shop are retyped into accounting by the accountant.
  • Supplier prices are updated by hand.
  • Endless security updates.

How we do it

  • One system and one admin area.
  • Once an order is paid, the invoice is issued in accounting and sent to the buyer.
  • Supplier price lists and stock are updated on a schedule.
  • We look after the server, updates and monitoring.

How it works

The chain from payment to accounting

From the buyer’s payment to the accountant’s screen — without retyping.

  1. 01

    The buyer pays

    The order is paid online by bank link or card.

  2. 02

    The invoice is issued in JARS Apskaita

    The invoice is issued in accounting, and the PDF is e-mailed to the buyer. This chain has been running in a client’s online store since late August 2026.

  3. 03

    The accountant already sees it

    The sale is recorded in accounting — nothing to retype.

  4. 04

    Supplier prices and stock

    Supplier price lists are loaded on a schedule, and prices are recalculated by your rules.

  5. 05

    SEO and ad accounts

    We set up Search Console, analytics and ad accounts so that you can start marketing right away.

    Server, updates, monitoring and integration upkeep.

About JARS Apskaita

Stages

From the first conversation to a working shop

  1. 01

    The first stage

    We launch the core of the shop with its admin area. If there are unknowns, such as your accounting program’s interface, we clarify them first and deliver a decisions document with a fixed price. You can order the first stage on its own.

  2. 02

    The next stages

    Integrations, suppliers, delivery and marketplaces — stage by stage. After the first stage we fix the budget of each next stage; if more hours are needed, we cover them.

  3. 03

    Maintenance

    Server, updates, monitoring and integration upkeep — for a monthly fee, with no percentage of turnover.

How we work

Clear rules from the first conversation

  1. In stages

    Every stage ends with something that works, not a report. You can order the first one on its own.

  2. Fixed budget

    After the first stage we fix the price of the rest. If it takes more hours, we pay for them.

  3. 0 % of turnover

    No percentage of your sales and no platform licence fees.

  4. Your data

    Customers, orders and their history belong to you. Every stage comes with a 6-month warranty.

Questions

Frequently asked questions

How much does it cost?

The price depends on the scope, so we start with a first stage that you can order on its own. After it you know the exact price of the next stages: we fix it, and if more hours are needed, we cover them. We take no percentage of turnover.

Can I keep my accounting program?

Yes. JARS Apskaita connects right away, and your current system (e.g. Rivilė, Centas, Finvalda) is assessed in stage 1: we check how it connects and only then fix the integration price.

Will I be able to change texts and prices myself?

Yes. You change texts, prices, photos and products in the admin area without a programmer, and many products can be uploaded as a CSV or Excel file from a template.

What if I decide to work with someone else?

Your data is yours. Clients, orders and their history belong to you, and we hand them over if you move to another team.

Do you run advertising?

We set up and configure Google Ads, Merchant Center and Meta accounts and conversion tracking. Campaigns are run by you or your marketer.

How long does it take?

Usually 3 to 8 weeks: a small website with a shop is quicker, integrations with existing systems take longer. You know the exact timeline after the first stage.
