Book a diagnostic

Thirty minutes and we tell you what your system is costing you.

You tell us how you work today and we tell you where the hours and the money go. If your system holds up, we say that too — no hard feelings.

Sample diary: write to us and we’ll give you a time.

Information on how we handle your data

Controller: Earningcode S.L.U., tax ID (CIF) B13569314, C/ José María Serna 5, local, Tomelloso (Ciudad Real), Spain. Purpose: to handle your diagnostic, contact or access request and follow it up commercially. Legal basis: your consent and the pre-contractual steps you ask for by writing to us. Recipients: none outside Earningcode S.L.U., unless required by law. Retention: for as long as the commercial relationship lasts, or until you withdraw your consent. Rights: access, rectification, erasure, objection, restriction and portability, by writing to privacidad@larstel.com. More in the privacy policy.

Tell us in the message how many SKUs you carry, how many delivery routes you run and what hurts most right now. That is what we prepare the half hour with. If you would rather use the phone, dial 625 110 647.

If you would rather meet in person, we are in Madrid, Barcelona and Tomelloso.

What we don’t ask you for

No access to your current systems
No files with your customers’ data
No minimum term and no small print

What you’ll see on the call

3 screens
Screen 1 of 3

Map of your operation

Where the same data gets keyed in twice.
Sample data
Order by phone notebook → Excel → delivery note 3 times
Goods out of the warehouse paper → stock sheet 2 times
Delivery note from the route paper → invoice 2 times
Invoice and accounts accounting software 2 times
Payment and reminder bank → risk spreadsheet 2 times

Eleven manual entries for an order that comes in once.

Screen 2 of 3

The three leaks, in euros

What carrying on like this costs a year.
Sample data
Hours spent matching paperwork 2 people · 1.5 h/day €18,400
Waste from expiry dates nobody flagged 0.9% of purchases €11,700
Shortages delivered late 3 orders/week €9,200
What a year like this costs example €39,300

Sample figures for a typical distributor. Yours come out of your own data in the diagnostic, and they are current cost: what it costs you to work this way today. They are not a promised saving.

Screen 3 of 3

Rollout plan

What happens, when, and who does it.
Sample data
Catalogue and customers migrated we do it Week 1
Orders and warehouse running 2 h training Week 2
Routes and driver app with your drivers Week 3
Invoicing and payments running alongside the old system Week 4
Old system switched off no going back Week 6

With dates and a closed price. If the timing doesn’t work, we say so before signing.

Sample plan for a simple start-up. Every plan runs from 30 to 90 days and is set in the diagnostic.

03After you send it

What happens after you hit send.

Four steps, each with a time on it. None of them depends on you chasing us: if we ever miss the deadline, we call you to say so.

The report you take away

Nine pages. Yours, whether you sign or not.

It’s not a Larstel pitch: it’s your operation written out with numbers. It’s worth having even if you end up building something else.

Confirmation with a time

You get an email with the day, the time and who’s going to call you. None of that “we’ll be in touch”.

04Before you book

What people ask us before taking a slot.

Three questions that come up on almost every call. If you still have another one, ask it by phone before filling in anything.

Direct line

625 110 647

Is this a sales call?

No. Half an hour of questions about how you work. If the system you have today holds up, we tell you and we don’t call again.

Do I have to show you real data?

No need. One screen and a sample delivery note is enough. If you want your first daily brief built from your data, bring two files — stock and orders — and we sign a confidentiality agreement first.

What if I have no time this week?

You book it as far ahead as you need. If seven in the morning or eight in the evening suits you better, we do it then.

What it costs

€0
The diagnostic is free.
Not now, and not later if it doesn’t fit.
There’s no terms sheet to sign.

How long it takes

7 days
0 h: confirmation with a time.
48 h: report in your inbox.
Day 7: proposal with price and dates.

What you bring

2 h
30 minutes on the call.
A good hour showing us how you work.
Not one piece of your data leaves Earningcode.

The price of the ERP is settled in the day-7 proposal, with scope and dates in writing. No small print and no minimum term hidden in an annex.

Projects start from €20,000. The exact figure comes out of the diagnostic, and the diagnostic is free.

Or we call you.

If you’d rather not fill in anything, dial this number and we book it by phone in two minutes.

Thirty minutes, no obligation. If your system is fine, we’ll tell you that too.
