Everything for your website

From fixing a single error to connecting payments, couriers and accounting software.

I fix:

  • Paysera and Montonio payments
  • Omniva, DPD & LP Express shipping
  • product import from suppliers
  • the connection to your accounting software
  • visibility in Google search (SEO)
  • old OpenCart 1.5 shops

I repair and update online shops and websites that are already running, so that they look good on phones, the cart and payments work, and no errors or outdated, unsafe system versions are left.

Send me your website address. I will look at it and tell you what I would fix.

I work with WordPress and WooCommerce, OpenCart (also very old versions), PrestaShop, Magento, Joomla, Drupal and custom-built PHP websites.

Write what you need

Common problems

This is how owners usually describe problems. For each one, I wrote how I fix it.

  1. “On phones the text and buttons are too small, so buyers leave.”

    I adapt the shop for phones: the text is easy to read, and the menu, product pages and cart are easy to use with one hand.

  2. “The browser says the website is not secure.”

    I install an SSL certificate (HTTPS), so the browser no longer warns that the site is not secure. I redirect the old http:// addresses to the new https:// ones, so your pages stay in Google search.

  3. “A menu link leads to an error page.”

    I fix broken links (404 errors) and PHP errors.

  4. “We need to connect Paysera and couriers.”

    I connect payment methods (such as Paysera) and couriers, and set up automatic shipping cost calculation.

  5. “The shop is old, and we are afraid to change anything.”

    I update shops on very old versions too, for example OpenCart 1.5. First I make a backup copy, then I test the changes in a test copy, and your shop keeps working in the meantime.

Work I have done

So far I have worked mostly on the online shops of UAB Siuvimo manija. To be upfront: it is my family's company.

OpenCart · shop since about 2010

siuvimomanija.lt

Client · OpenCart · hunting gear shop

e.segris.lt

An old hunting gear shop running on OpenCart. The shop got a new look, and the products got descriptions in Lithuanian.

  • New look for phones and computers
  • SSL (HTTPS) fixed
  • Product descriptions in Lithuanian with photos and video
  • Visibility in Google search improved (SEO)

Before and after

Desktop

The old e.segris.lt home page on a desktop: a narrow centred layout on a wood-texture background, a round logo, a dark menu bar and a Work Sharp promo banner.
The new e.segris.lt home page on a desktop: a dark green header with the SEGRIS name, a wide search field and a full-width Work Sharp sharpener section with clear buttons.

Phone

The old e.segris.lt on a phone: four grey icons at the top, a large logo, a small search field, and a promo banner that is cut off because it does not fit the screen width.
The new e.segris.lt on a phone: a compact green header with search and a menu button, an image and text that fit the phone screen, and large buttons that are easy to tap.

Product page

The old e.segris.lt product page: a long category menu on the left, a breadcrumb in reverse order and the product name repeated three times.
The new product page for the same Work Sharp sharpener: a correct breadcrumb, a large product photo, a clear name and a separate buy box with stock status and an add-to-cart button.

Drag the line to compare.

How I work

While I work on it, your shop runs as usual.

  1. I review and write to you

    I look at the website and tell you in writing what I would do and what it would cost. This is free.

  2. I make a backup copy

    I copy the whole website and the database, so I can restore everything if needed.

  3. I fix it in a test copy

    I make and test all changes in a test copy first, not in your shop. Your shop keeps taking orders in the meantime.

  4. I move the changes

    When everything is checked, I move the changes into your live shop.

Payment

Before I start, we agree on the price and sign a contract. You pay in parts: for larger jobs, you pay an advance before the work starts and the rest when the work is done and checked. VAT invoices are issued by UAB Siuvimo manija (Lithuania). For a business in another EU country with a valid VAT number, the reverse charge applies: no Lithuanian VAT is added. I check the VAT number in VIES, the EU's VAT number check.

Full terms

Access

For the work I need access to the admin panel, the website files (FTP or SFTP) and the database, for example through your hosting control panel (DirectAdmin, cPanel or Plesk). I do not work on Shopify, Wix or Squarespace shops, because these systems do not provide access to the files.

Monthly maintenance – €55/month + VAT

Write what you need

Every month

  • I update the system and plugins
  • I make backup copies
  • I check the SSL certificate and watch for errors
  • I keep the SEO basics up to date: titles and descriptions of new products and pages, and the sitemap

The price also includes about an hour of small jobs per month.
