Free forever up to 10 units · No credit card · Founder pricing: the first 20 dealers to upgrade keep the prices below
Dealers leak money in 3 places.
Three predictable revenue patterns we see across every dealer we audit — and roughly what each one costs a mid-sized fleet per year.
Forgotten warranty renewals
Average dealer misses 8 warranty renewals per year. Each one is a lost service contract.
~8 missed renewals × $300 service contract
Missed battery replacements
Battery cycles end at year 5. Without alerts, customers replace through your competitor.
~12-unit fleet × 5-yr cycle × $700 replacement
Skipped PM visits
Preventive maintenance contracts go unbilled when nobody tracks the calendar.
~4 quarterly visits × $800 dispatch fee

Common questions.
Is there a free plan?▾
Yes — Power Stack is free forever for up to 10 installed units. Full access to every feature, no time limit, no credit card. If you need to track more than 10 units, pick a paid tier whenever you are ready. Nothing is charged until you choose to upgrade.
Does it work with all UPS brands or just yours?▾
All brands. ATENCO, Schneider, Vertiv, Eaton, APC, Mitsubishi, Riello, Socomec, Kstar, Huawei, Delta — every brand a dealer sells. Brand-agnostic is the entire point.
What if my data is in WhatsApp screenshots and Excel sheets?▾
That is most dealers. Send us what you have. Our team imports everything during onboarding. You do not need to be a software person.
What languages?▾
English at launch. Additional languages on request — let us know what you need.
Where is my data stored?▾
Supabase (Postgres) infrastructure with row-level isolation per dealership. Your data is never visible to other dealers. Encrypted at rest and in transit.
What happens when I reach 10 units?▾
Nothing breaks. The dashboard tells you the free plan is full, and the 10 units you already have keep every feature and every alert. Adding an 11th means choosing a paid tier. Paid upgrades are opening shortly; if you are over 10 units before then, email us and we will sort it out by hand.
What is founder pricing?▾
The monthly prices on this page are the launch prices. The first 20 dealers who upgrade to a paid tier keep them for as long as they stay subscribed; after that, new sign-ups pay standard pricing. The free tier is not affected either way.
What alerts do you actually send?▾
A daily check messages your primary WhatsApp number when a warranty ends within 30 days, a PM visit is due within 7 days, or a battery replacement is due within 30 days. A weekly email every Monday summarises what is coming up over the next 30–90 days and what changed last week. The weekly email can be switched off in Settings; WhatsApp preferences are coming.
Do I need an account to use the engineering calculators?▾
No. All 13 calculators are free, anonymous and work on a phone. Every result has a share link and a Save-as-PDF button. They are engineering aids backed by the standards named on each page — not a substitute for the OEM datasheet or a licensed engineer’s sign-off.
Can I export my data or cancel?▾
Yes. Your installed base, customers and tickets are yours. The reports export to PDF today; a full CSV export is on the roadmap, and in the meantime email us and we will send a complete export within a few days. Cancel whenever you like — we keep your data for 30 days in case you come back, then delete it, as set out in the Privacy Notice.
Start free. Lock founder pricing.
The first 20 dealers who upgrade keep today’s prices for as long as they subscribe. The free tier stays free regardless.
