Pay for PmWiki development

Make a payment

Ongoing operation & technical support
of PmWiki wiki services (Petko Yotov)


Name and Address for invoice:

Major credit and debit cards accepted

SEPA/IBAN bank transfer: Contact us

PmWiki is open source and available free of charge, however the "free" time for its development, maintenance and support is limited.

If you or your organization benefit from PmWiki and its development, you can support future development, growth, and maintenance by making a payment. You will receive invoices and may be able to deduct them as expenses.

Petko Yotov has been the PmWiki core developer, release manager and webmaster since 2009, and has been publishing addons, updating documentation and providing support since 2006. Financial contributions allow Petko to dedicate more time and effort to the project, reduce other "real" (paid) work and still take care of family, rent, and food. Payments also reduce the tensions among family, work, and PmWiki and reduce burnout on the project.

Do not feel obligated to make payments: you can always get PmWiki and support for free. This page exists to allow people or companies who want to contribute to do it legally and easily.

Details...

Payments can be made via SEPA/IBAN bank transfer, via Credit Card or via PayPal, and you will receive an invoice.

  • SEPA/IBAN bank transfer: the best and least expensive payment from a bank account in EUR is via a SEPA/IBAN bank transfer. Please contact 5ko@5ko.fr for details. European companies and individuals from the EuroZone may prefer this method. Non-EU companies can also use this method, contact your bank for confirmation.
  • Payment cards: Credit or Debit cards, or PayPal accounts can be used to make payments, fill in the form.

While development, documentation, maintenance, communications, testing, and a host of other costs vary considerably according to the activity and complexity, below are some rough details on what your payments can allow Petko to perform:

  • 320 EUR = a day's work, eg. Core development (planning, researching, coding, testing, committing, documenting).
  • 320 EUR = pmwiki.org website maintenance for 1 month (reviewing edits/uploads, reverting spam & vandalism, fixing broken pages, cleanup, configuration).
  • 160 EUR = tech intelligence gathering for 1 month (threats, strategies).
  • 160 EUR = fix and document 1 medium bug, or 2 simple bugs, or review & update 4 addons for PHP compatibility.
  • 480 EUR = create a simple mobile-friendly skin, or an average complexity addon.
  • Communication (English is Petko's third language so writing takes some effort).
    • 40 EUR = reply to support or development questions (4-5 simple/short replies, or 1 long reply, or 1 reply requiring research/testing/sample code).
    • 160 EUR = update the PmWeekly? reference log for a month.
