How to track warranties, servicing and important deadlines

Why a receipt in a drawer is not enough

A receipt confirms the purchase but reminds you of nothing. It sits in a drawer or as a photo in the gallery and gets found only once the device has already broken — often weeks after the warranty expired.

The problem is not a shortage of documents but the absence of a moment when something reminds you about them. An effective system combines three elements:

• A date you have to meet.
• A reminder set early enough that you can still act on it.
• Context — what it concerns, where the proof of purchase is, who to call.

Without the third element, a reminder saying "warranty expires tomorrow" forces you to work out which device it means. Without the second, you find out about everything too late.

Which deadlines are worth tracking

Recording everything ends the same way as an over-detailed shopping list: you stop reading it. It pays to limit yourself to events whose omission genuinely costs something.

The deadlines that cost the most

Cycles and legal obligations differ between countries — the values above are typical ranges worth comparing against local requirements.

Small but annoying deadlines

The second group carries no penalty, but without a reminder it usually slips your mind: replacing water and extractor filters, changing tyres, bicycle servicing, air-conditioning checks, smoke-detector batteries, renewing subscriptions and domains, extending documents.

Manufacturer's warranty and your statutory rights

Many people track only the manufacturer's warranty, unaware that a faulty product usually gives them two separate routes to a remedy.

The warranty

This is a voluntary commitment from the manufacturer or seller. Its length and scope are set out in the warranty card — most often 24 months, sometimes 12 or 36, and longer for certain components. Claims normally go to a service centre named by the manufacturer.

Rights under the law

Regardless of any warranty, consumers have rights against the seller that come from legislation. In the European Union the minimum period of seller liability for goods not conforming to the contract is two years from delivery, and individual countries may provide more generous terms. The name of this mechanism and its detailed rules vary between jurisdictions, and claims are directed at the shop where the purchase was made.

The practical conclusion for a reminder system: record the purchase date, not just "warranty end". Both periods run from it, and it is the reference point in any dispute.

How far ahead to set the reminder

The most common mistake is a reminder set for the day of the deadline. The information arrives when nothing can be done about it.

The lead time should match how long the task actually takes to arrange:

• 7 days — things you can handle immediately: changing a filter, a small purchase, a payment.
• 14 days — anything needing an appointment: a roadworthiness test, bicycle service, air-conditioning check.
• 30 days — matters that involve comparing offers: home insurance, motor insurance, subscriptions.
• 60 days — the end of a warranty on expensive equipment. That margin gives you time to check the device works properly and report a fault while it is still covered.

What to put in the note

A reminder with nothing but a name forces you to hunt for details at the exact moment you need to act. A few lines in the note save a quarter of an hour.

• Document number — policy, contract or service order.
• Contact — phone number for the service centre, garage or agent.
• What to bring — proof of purchase, warranty card, the previous report.
• Where the original is — "folder in the wardrobe, divider 3".
• Last year's amount — a reference point when negotiating or comparing offers.

Recurring deadlines

Most important deadlines come round every year. Setting them again from scratch each time is the simplest route to missing one — forget to add the next date just once and it is gone.

Recurring deadlines are worth setting for: roadworthiness tests, motor insurance, home insurance, boiler and chimney inspections, changing tyres (twice a year), air-conditioning checks, filter replacements, annual fees and subscriptions.

Check the next date after completing a task

This is where errors most often creep in. After ticking a deadline off, glance at whether the next date has been set correctly — particularly for anything that is not exactly annual, such as an inspection every 18 or 24 months.

Linking a deadline to an item

A reminder saying "warranty ends" without naming the device is close to useless — especially a year later, when nobody remembers what it referred to.

When a deadline is linked to a specific thing, the reminder gives you immediate access to the purchase date and place, the value, photos of the rating plate and any notes. If something fails, everything is in one place and filing a claim takes minutes rather than an evening spent looking for the receipt.

That does of course require the equipment to have been recorded first. How to do that efficiently, without cataloguing every last trinket, is covered in our guide to creating a home inventory step by step.

Setting the system up in one evening

The whole system can be running in about an hour. The order that works best:

1. Write out the deadlines from memory (10 min). Car, home, boiler, subscriptions. That usually comes to 6–10 entries.
2. Find the documents (20 min). Policies, warranty cards, inspection reports. While you are at it, photograph any you do not have in digital form.
3. Enter the deadlines with lead times and notes (20 min). Start with the most expensive consequences: motor insurance, roadworthiness test, home insurance, boiler.
4. Set the recurrence (5 min) for everything that comes round annually.
5. Add warranties while you are there (5 min) — for now only for the most expensive items bought in the last two years.

After that evening the system is running. New deadlines get added one at a time, as you buy things.

Set your first reminders in minutes

In Domowik a deadline can be linked to a specific item, so the reminder arrives with the purchase date and documents attached.

Common mistakes

• A reminder on the day itself. The information arrives when you can no longer react. Lead time should match how long the task takes to arrange.
• A deadline with no context. "Warranty" or "inspection" without saying what it covers forces you to go searching at the worst possible moment.
• Recording only the warranty end date. The purchase date matters more — statutory rights run from it too.
• Retyping deadlines manually every year. One lapse and the deadline disappears from the system for good.
• Not checking the date after ticking something off. For cycles other than annual, the next date often lands somewhere other than you assumed.
• Recording everything. Thirty reminders a month means you stop reading them, including the important ones.
• Relying on memory for equipment under warranty. Two years is far too long to remember when you bought a washing machine.

How Domowik can help

This kind of system can be run in a phone calendar, and for some people that is enough. The calendar's limitation is that an event is not connected to the thing it concerns — the date exists separately from purchase details and photos.

In Domowik, deadlines can be general or assigned to a specific item, which supplies the context described above. There is a list view of upcoming matters and a monthly calendar view, and notifications work locally on the device. Deadlines can be exported to an ICS file, and an individual deadline can be passed to Google Calendar if you prefer to have it there as well.

Data stays on the device and does not sync automatically, so it is worth making a copy before changing phones — covered separately in our guide to backing up app data before changing phones.
