DocMak Tools & Document Automation Resources

Every commercial, corporate and HR document an engineering supplier issues — quotations, invoices, company profiles, board resolutions, employment certificates and contracts — generated from structured templates rather than reformatted by hand. Browse the full catalogue on the DocMak document automation tools directory.

CV, Career & Company Profile Documents

Build the credentials pack that engineering contractors, operators and tender committees ask for — a CV, a covering letter, a company profile and the supporting certificates — without wrestling with page layout.

Online CV Maker

A structured CV builder for engineers, technicians and project professionals. Enter your experience, projects, certifications and technical skills, then export a clean, ATS-readable PDF in an oilfield-appropriate layout. Section templates cover well-services experience, HSE training, competency matrices and equipment exposure, so recruiters see the details that matter for upstream and process-industry roles instead of a generic résumé template.

Primary use case
Job applications, tender key-personnel CVs, consultant profiles.

Cover Letter Maker

Pairs with the CV builder to produce a role-specific covering letter. Choose a tone, add the hiring company and role, and the tool structures an opening, an evidence paragraph tied to your project record and a clear close. Useful when submitting key-personnel packs where each nominated engineer needs a distinct letter rather than a copied template.

Primary use case
Recruitment submissions and pre-qualification personnel packs.

Company Profile Maker

Assembles a corporate profile document covering company background, licences, service lines, HSE record, reference projects and key personnel. Designed for suppliers registering with national oil companies and EPC contractors, where a consistent, well-presented profile is a scored part of vendor pre-qualification. Export as PDF for portal upload or as an editable file for future revisions.

Primary use case
Vendor registration, pre-qualification and bid submissions.

Letterhead Generator

Creates a consistent branded letterhead with logo placement, licence numbers, registered address and footer contact block. Applies across correspondence, technical transmittals and commercial letters so every document leaving the business carries the same identity — a small detail that carries weight in formal tender correspondence.

Primary use case
Formal correspondence, transmittals and commercial letters.

Invoicing, Quotation & Commercial Document Tools

Quotation-to-cash paperwork for service companies and suppliers: quotations, purchase orders, invoices, proforma invoices, delivery notes and credit notes, with UAE VAT handled correctly.

Invoice Maker

Generates numbered tax invoices with line items, discounts, VAT treatment, payment terms and bank details. UAE-specific fields cover TRN, place of supply and reverse-charge notes so invoices satisfy FTA requirements on first submission. Useful for well-services contractors and chemical suppliers billing against call-off orders where invoice rejection delays payment by a full cycle.

Primary use case
Billing completed work, call-off orders and milestone payments.

Raise a compliant tax invoice with the DocMak Invoice Maker

Try the Invoice Maker

Proforma Invoice Maker

Produces a proforma invoice for buyers who need a document to open a letter of credit, release an advance payment or clear internal budget approval before goods ship. Captures Incoterms, currency, validity period, packing details and estimated freight so the commercial position is unambiguous before the commercial invoice is raised.

Primary use case
Advance payments, LC opening and import documentation.

Proposal Maker

Combines a technical narrative, methodology, schedule and pricing table into a single proposal document. Suited to engineering studies and stimulation campaign proposals where the evaluation is split between technical merit and commercial score, and a coherent document structure directly affects the mark awarded.

Primary use case
Tender responses and consultancy proposals.

Payment & Expense Voucher Makers

Generates internal payment vouchers and expense claim vouchers with approval blocks, cost-centre coding and supporting-document references. Keeps field expense reimbursement and petty-cash disbursement documented to the standard an external auditor expects, without maintaining a separate accounting template library.

Primary use case
Internal approvals, field expenses and petty cash.

Board, Shareholder & Meeting Documentation

Corporate governance records — agendas, minutes, board and shareholder resolutions, certificates of incumbency — in the format banks, registrars and auditors accept.

Meeting Minutes Generator

Turns discussion notes into formal minutes with attendance, decisions, actions, owners and due dates separated out. Action registers export cleanly for tracking, which matters on multi-party well-intervention reviews where an undocumented agreement between operator and service company becomes a commercial dispute months later.

Primary use case
Formal minutes, action tracking and audit evidence.

Shareholder Resolution Maker

Produces written shareholder resolutions covering capital changes, director appointments, dividend declarations, constitutional amendments and authority to sign. Includes quorum wording, signature blocks and dating conventions that registrars and banks check when a resolution is submitted in support of an account change or licence amendment.

Primary use case
Corporate changes, bank mandates and licence amendments.

HR, Employment & Experience Certificates

Employment paperwork across the employee lifecycle: offer letters, contracts, salary and experience certificates, NOCs, verification letters and warning letters.

Experience Certificate Maker

Produces an experience or service certificate confirming role, employment dates, responsibilities and conduct. Engineers submitting for professional registration, visa processing or competency accreditation are routinely asked for this document, and the receiving body rejects informal letters that omit dates, designation history or an authorised signature block.

Primary use case
Professional registration, visas and competency accreditation.

Issue a service experience certificate with DocMak

Try the Experience Certificate Maker

Employment Offer Letter & Contract Makers

Covers the hiring pair: a conditional offer letter with package summary and acceptance block, and a full employment contract with duties, probation, notice, leave, confidentiality and termination clauses. Rotational and site-based terms can be reflected explicitly, which standard office templates rarely handle.

Primary use case
Hiring, mobilisation and rotational field staff.

Contracts, Labelling & PDF Utilities

Agreement drafting, chemical and shipping labelling, and the PDF handling tools that surround document submission.

NDA Generator

Generates confidentiality agreements with definable scope, duration, permitted-disclosure carve-outs and governing law. Standard practice before sharing reservoir data, treatment designs or production histories with a service provider during a technical evaluation, and quick enough to issue in the same conversation the data request is made.

Primary use case
Technical evaluations, data rooms and vendor discussions.

Partnership, JV & MOU Generators

Covers the pre-contract and partnership stages: memoranda of understanding to record intent before commercial terms are settled, plus partnership and joint-venture agreements defining contributions, profit share, governance and exit. Frequently used when local and international parties form a bidding entity for a field-services tender.

Primary use case
Consortium bidding and joint ventures.

Distribution & Sale of Goods Agreement Makers

Produces distribution agreements with territory, minimum volumes and pricing mechanics, and sale-of-goods contracts covering specification, Incoterms, inspection, title transfer and remedies for non-conforming cargo. Directly relevant to chemical and commodity supply where quality disputes turn on the inspection clause.

Primary use case
Chemical distribution and commodity supply contracts.

PDF Toolkit

Utilities for the final step before submission: merge a technical bid into a single file, split an oversized attachment, compress to meet a portal upload limit, convert PDF to Word for editing, or combine scanned JPGs into one document. Tender portals reject files on size and format far more often than on content.

Primary use case
Tender submission, portal uploads and document handling.

Tradloc Commodity Trading & Market Intelligence Resources

Indicative pricing for chemicals, petrochemicals, metals, minerals, polymers and grains, plus the freight, duty and landed-cost calculators that turn an ex-works quote into a delivered cost. Start from the Tradloc commodity trading and market intelligence platform.

Commodity Price Intelligence & Market Estimators

Indicative pricing across chemicals, petrochemicals, metals, minerals, plastics, fertilizers and food grains — the reference layer for budgeting a purchase before an RFQ goes out.

Chemical Price Estimator

Indicative price ranges for industrial chemicals by grade, packaging and origin. For oilfield procurement teams budgeting acid systems, corrosion inhibitors, biocides and scale inhibitors, it establishes whether a supplier quotation sits inside the market band before the negotiation starts.

Primary use case
Budgeting chemical purchases and benchmarking supplier quotes.

Shipping, Freight & Landed Cost Tools

The logistics half of a delivered price: ocean freight, transit time, container utilisation, customs duty and total landed cost.

CBM, Pallet & Container Loading Calculators

Volumetric planning tools: cubic-metre calculation from package dimensions, pallet configuration, and how many units fit a 20ft, 40ft or high-cube container. Prevents the common error of paying for a half-empty container on drummed chemical shipments where weight limits out long before volume does — or the reverse.

Primary use case
Packing optimisation and shipment consolidation.

Open the Loading Calculator

HS Code Finder & Customs Clearance Estimator

Classification lookup to identify the correct HS code for a product, plus an estimate of clearance charges and timeline at destination. Misclassification of oilfield chemicals is a routine cause of port detention, demurrage and retrospective duty assessment, so the code is worth confirming before the shipment is booked.

Primary use case
Customs classification and clearance planning.

Knowledge Center FAQ

What is the KEMISIM Knowledge Center?
A single reference hub covering three areas: reservoir and well engineering methodology behind the KEMISIM software suite, document automation tools from DocMak, and commodity pricing, shipping and sourcing resources from Tradloc.
Are the DocMak and Tradloc tools free to use?
Each tool page on DocMak and Tradloc states its own access terms. Most document generators and estimators can be used directly from the linked module page without installation.
How do these resources relate to oilfield operations?
Engineering guides cover treatment design and evaluation. Document tools cover the tender, contract and invoicing paperwork around a job. Trade tools cover chemical pricing, supplier verification and delivered cost — the procurement side of executing a campaign.
Where should I start?
Engineers should start with the engineering references. Commercial and procurement teams should start with the invoicing guide and the commodity trading guide, both of which link out to the specific tools at each step.
