How can we help?

FieldForge is a voice-powered invoicing system built for field service businesses — HVAC, plumbing, and electrical. A tech records a voice note describing the job, and FieldForge automatically builds a professional PDF invoice, sends it to the customer via SMS, and tracks payment. Everything happens through Telegram.

Open Telegram, search for @UseFieldForgeBot, and send the message REQUEST ACCESS. Fill in your name, company, and email when prompted. You'll receive an owner invite code after approval (typically within 1 business day). Then send START ONBOARDING to begin setup.

Just Telegram — which is free on iOS and Android. Your customers don't install anything either. They receive an SMS with the invoice and payment link.

Under 10 minutes for the owner. The bot walks you through each step: entering your hourly rate, tax rate, company phone, and optionally a payment link. Techs register in under 2 minutes using an invite code you generate.

The bot will ask for: your company name, owner name, hourly labor rate (e.g. 95 for $95/hr), tax rate (e.g. 8.5 for 8.5%), company phone number, and optionally a payment link for your customers. That's it.

Send ADD TECH to the bot. You'll receive a unique TECH- invite code. Share that code with your technician — they open the bot, type the code, and register in about 2 minutes. To see all your techs, send MY TECHS.

Currently: HVAC, Plumbing, and Electrical. Each trade gets a pre-loaded parts price sheet with 50 common parts for that trade. More trades are coming — let us know which you'd like to see next.

A Google Sheet created specifically for your company during onboarding, pre-loaded with 50 common parts for your trade. The AI reads this sheet every time you submit a voice note and uses your prices to build the invoice.

The bot sends you the Google Sheets link at the end of onboarding. You can also find it in your Google Drive. You were granted editor access using the email address you provided during setup.

Yes. Just add a new row to the Parts List tab in your Google Sheet. Include the part name, part number, unit price, and optionally a common alias. Changes take effect on your next voice note — no restart needed.

Yes. Edit the Unit Price column directly in Google Sheets. The AI uses your current prices every time, so changes are immediate.

An alternate name for a part that helps the AI make the right match from your voice description. For example, if your sheet lists "Wax Ring" but a tech says "wax seal," the alias ensures the AI picks the correct part. You can add multiple aliases per part.

Review the invoice summary the bot sends before it reaches the customer. If something looks off, you'll see a low confidence warning (⚠️) from the bot. Add a common alias for that part in your sheet to prevent it in the future.

Yes — just delete the row from your Google Sheet. The AI only searches parts that are in the sheet.

Include: the customer's name, their address or location, what parts you used, how long the job took, and the customer's phone number. Example: "Johnson on 123 Oak Street, replaced the capacitor and cleaned the coils, 2.5 hours, customer phone is 404-555-1234." The AI handles the rest.

Very accurate for standard field descriptions. The bot shows a confidence score after each job. If confidence is below 80%, you'll receive a warning prompt to review the invoice before it goes out. Accuracy improves as you keep your parts sheet and aliases up to date.

Your hourly rate × the time mentioned in the voice note. For example, if your rate is $95/hr and the tech says "2.5 hours," labor = $237.50. Your hourly rate is set during onboarding and can be updated anytime.

Via SMS to the customer's phone number mentioned in the voice note. The message includes a link to the PDF and a payment link. No email, no app required for the customer.

Yes. Send RESEND JOB-xxxx with the Job ID (visible in the original invoice message from the bot). The bot will reply with the PDF link so you can forward it to the customer.

Yes, on Starter and above. Send HISTORY [customer name] — for example HISTORY Johnson. The bot returns up to 5 matching jobs with the amount and Job ID. All your job data is also available in your Google Sheets jobs tab.

The bot notifies you when you've reached your monthly invoice limit. You won't be able to create new invoices until the 1st of the next month (when counters reset) or until you upgrade your plan. Send UPGRADE or CHANGE PLAN to increase your limit immediately.

Yes. Send CANCEL to the bot. Your plan stays active until the end of your billing period. After that, you automatically move to the Free plan (1 tech, 20 invoices/month). Your data is never deleted.

Yes. Upgrades apply immediately — you're charged the prorated difference. Downgrades are scheduled to apply at the end of your current billing period. Send CHANGE PLAN to manage your plan.

Share your referral code with another field service business owner. When they sign up and enter your code during onboarding, you earn 1 free month — automatically applied to your next billing cycle. Send REFERRAL to get your code. There's no limit on how many referrals you can make.

Everything stays in your Google Sheet — jobs, invoices, customer info, everything. The data is yours and we don't remove it when you downgrade or cancel.

Billing is handled by Stripe — secure, monthly, and automatic. You receive a receipt after each charge. Manage your subscription entirely through @UseFieldForgeBot — no web portal needed.
